The research group has a well-established experience in the study of blood coagulation factors, including i) the analysis of intracellular and plasma expression levels, ii) the characterization of natural and engineered protein variants by expression studies in eukaryotic cells, and iii) their specific transcriptional, post-transcriptional and translational modulation.
The scientific activity of the group is demonstrated by several publications in international peer-reviewed journals.
Our activity is focused on the investigation of the efficiency of blood coagulation cascade in plasma samples from patients affected by coagulation disorders, or in deficient plasma supplemented with recombinant proteins of interest. To this purpose in our laboratory we have optimized small scale functional assays with specific fluorogenic substrates that permit us to monitor the initiation (generation of activated factor X) and amplification (generation of thrombin) phase of coagulation.
These approaches have been used for the biochemical characterization of natural and engineered protein variants of coagulation factors produced by recombinant technologies and expression in eukaryotic cells.
The haemostatic process is tightly regulated through a balance of anti- and pro-coagulant protein components, such as factor VII, factor IX, factor X and thrombin.
Alterations in plasma levels of these proteins, due to genetic or acquired factors (including pharmacological treatments) cause haemorrhagic or pro-thrombotic events whose clinical relevance depends on their relative quantitative variation. The characterization of altered protein levels of specific factors and their effects on physiological processes can be obtained through functional studies performed on plasma samples. Together with traditional coagulation assays, we have optimized functional assays that permit us to evaluate the efficiency of the blood coagulation cascade at different levels, from the initiation to the amplification phase, including the generation of thrombin, which is the final effector of the whole process. These small scale assays take advantage of specific fluorogenic substrates. Moreover, we have developed binding assays to evaluate the interaction of coagulation factors with other molecules or complexes.
Data obtained by these methods can give information about the functional efficacy of blood coagulation both in humans and animal models, and can also be exploited for studies on biocompatibility of those biomaterials used for medical devices, such as dialysis systems or filters, which can come in contact with blood. Indeed, these interactions could lead to the activation or inhibition of coagulation cascade, or cause the depletion of specific proteins or macromolecular complexes, thus potentially leading to adverse events of physiopathological relevance. The knowledge of these aspects and multiple interactions pave the way for the design of the most suitable and compatible biomaterials or devices.
Functional assays
In our laboratory we have optimized small scale functional assays that enable us to monitor the initiation (generation of activated factor X) and amplification (generation of thrombin) phase of coagulation, in order to evaluate their efficiency in healthy patients or patients who experienced treatment/processing with devices of different nature (biocompatibility data). These assays are highly specific and sensitive. Analysis is performed on patient plasma samples, which are compared with pooled normal plasma used as reference. Moreover, the small scale features of these assays ensure the usage of microvolumes of samples and a high number of replicates, thus allowing highly consistent and reproducible data.
This Service also supplies with software-based analysis (GraphPad Prism) of the main parameters underlying the activity or coagulant capacity of the plasma samples tested.
ELISA and binding assays
Quantitative analysis through immunoenzymatic assays is available for specific coagulation factors.
Moreover, we have optimized ELISA-based binding assays on 96-well microplates for the evaluation of interactions between coagulation factors and other molecules or complexes.
This Service also supplies with software-based analysis (GraphPad Prism) of the binding constants describing the binding capacity of the tested molecules.
Mono- and two-dimensional electrophoresis

The innovative AlphaScreen® and the numerous Real-Time PCR applications represent key technologies of our core facility, which make it not only competitive, but also constantly expanding.
AlphaScreen® is the ideal detection technology which can simplify scheduling issues in screening the effects of bioactive molecules in terms of activity and biomolecular interactions. The approach relies on the use of donor (photosensitizer) and acceptor (chemiluminescer) beads, which are coated with proteins whose bioconjugation you intend to analyse. A fluorescent signal is produced when the AlphaScreenTM acceptor and donor beads are brought into proximity by a molecular interaction occurring between the binding partners captured on the beads.
Specifically, laser excitation of donor beads at 680 nm causes ambient oxygen to be converted to the singlet state by photosensitizers. The acceptor beads, on the other hand, contain a chemiluminescent agent, often a thioxene derivative, that reacts with the singlet oxygen, generating chemiluminescence at 370 nm. This energy is immediately transferred to the fluorophores contained in the same acceptor bead, which shifts the emission wavelength to 520-620 nm. The half-life of 0.3 seconds allows detection of fluorescence in time-resolved mode. The detection sensitivity is in the order of attomoles.
Real-time quantitative PCR allows the sensitive, specific and reproducible quantification of a target nucleic acid sequence in a biological sample in real time.
Real-Time PCR instruments not only act as thermal cyclers, but also excite the fluorophores contained in the samples and record the fluorescence in ‘real-time’ as the samples pass photodetection diodes within the instrument. A software acquires the emission spectrum form each fluorophore individually for the duration of the PCR and converts the variation in the reporter fluorescence to a real-time representation of the amplification kinetics.
Fluorescence is generated during PCR by different chemical reactions according to the binding of fluorescent dyes that intercalate in the DNA double helix, such as SYBR Green, or the hybridisation of specific probes. We use Real-Time PCR in:
TaqMan® Real-Time PCR
This technology is widely used in order to measure the expression level of a target sequence. A TaqMan probe is an oligonucleotide complementary to the target sequence to be amplified. The non-extendible hydrolysis (e.g. TaqMan®) probe bears a fluorophore at each end. In the intact probe, the fluorescence generated by the reporter dye in 5’ is quenched by the second fluorophore in 3’. Probe cleavage by the 5’-3’ exonuclease activity of the DNA polymerase during PCR extension releases the reporter and quencher moieties, then fluorescence is emitted and recorded. Unbound probes are not hydrolyzed and consequently, fluorescence is proportional to the quantity of the target product present.
Allelic Discrimination
This is a multiplexed assay (more than one probe per sample) which detects variants of a single nucleic acid sequence. The presence of two TaqMan® MGB (minor groove binder) probes in each reaction, both targeting the same SNP (single-nucleic polymorphism) site, one of them perfectly complementary to the wild type allele and the other to the mutated allele, allows genotyping of the two variants of a single-nucleic polymorphism site in a target sequence. The genotype is defined according to the relative intensity emitted by the two fluorophores.
High resolution melting (HRM)
This technique is based on the amplification of a gene of interest through real-time PCR and subsequent analysis of denaturation kinetic of the amplicons. HRM enables the different DNA sequences to be identified by melting curve analysis. Amplicons are denatured in the presence of an intercalating fluorophore that permits total saturation of DNA without inhibiting the PCR reaction. Saturation prevents relocation of fluorophores during the melting phase. Each duplex (homoduplex or heteroduplex) will exhibit a characteristic melting point in the denaturation phase. HRM records the change in the fluorescence that occurs during the dissociation stage from double strand DNA to single strand DNA.
High Resolution Melting (HRM) enables genomic researchers to detect and discriminate single bases mutations, insertions, deletions, base pair substitutions, polymorphisms and epigenetic differences in double-stranded DNA samples.

Our Service combines several decades of experience in the synthesis, purification and characterisation of organic, peptide and peptidomimetic molecules. In the course of our academic work we have identified many bioactive molecules capable of interacting with G protein-coupled receptors (GPCRs). In particular, compounds capable of interacting (as agonists, antagonists and partial agonists) with opioid receptors, the nociceptin receptor, the urotensin receptor and the neuropeptide S receptor. Various molecules identified by us here are now available commercially and used as reference standards in many academic and industrial laboratories working in the field of GPCRs.
The level of scientific work we do can be seen in many papers in prestigious international journals.
Recently, through a collaboration between the Neurology department of the hospital S.Anna di Ferrara and the Genzyme Corporation of Boston (USA), the efficacy of a recombinant enzyme (Myozyme) was demonstrated in the treatment of the rare metabolic condition, Pompe disease. Using mass spectrometry, the presence of marked glucose was evaluated in affected patients. As part of the same project a number of marked tetrasaccharides were identified in the urine of these patients.
HPLC (High Performance Liquid Chromatography) is an analytical tool derived from traditional chromatography and based on the same principles. In traditional chromatography the main component is the column that contains the stationary phase inside of which the mobile phase flows, represented by the eluent. The passage of the eluent occurs through the pressure exerted by the column of liquid forming the mobile phase and thus the process, if the stationary phase is not sufficiently porous, may also be very slow. Separation of the components occurs through the interactions that come about between the constituents of the mixture and the two phases. The interactions that occur may be electrostatic, dipole-dipole, van der Waals forces or else the result of an ionic exchange mechanism. This depends on the properties of both the two phases and the mixture to be separated. In HPLC the force that enables the eluent to flow down through the column is the pressure that is applied by a pump at the head of the column and that forces the mobile phase to flow inside the stationary phase. This not only makes the process quicker but also means that a greater number of theoretical plates can be obtained, which means a better resolution. The theoretical plate of a chromatography column corresponds to the section of a column where a chemical species is in equilibrium between the two phases (stationary and mobile) prior to the eluent drawing it into the next phase. However, the thinner the theoretical plate, the greater will be the efficiency of the column. The first positive developments in fluid chromatography were made after it was suggested and found that the theoretical plate could be made thinner by packing smaller particles into the column. The technology to make particles of sizes varying from 5 to 10 μm to pack into the column was not developed until the end of the 1960s. The name High Performance Liquid Chromatography (HPLC) serves to distinguish the new chromatography technique from traditional chromatography.
Mass spectrometry has been described as the smallest scale in the world, not because of the instrument’s size but because of the size of what it measures – molecular mass. Recent decades have seen considerable technological evolution in mass spectrometry, so that it is now possible to use it to determine peptides, proteins, nucleic acids, carbohydrates, drugs and other biologically relevant molecules.
Due to ionisation sources such as electrospray ionisation (ESI) and matrix-assisted laser desorption/ ionisation (MALDI), mass spectrometry has become an irreplaceable tool in biological science.
A mass spectrometer determines the mass, i.e. the molecular mass, of molecules by measuring the mass-to-charge ratio (m/z) of its ion. The ions necessary for this determination are generated by inducing either the loss or gain of a charge from neutral molecules. Once formed, the charged ions are directed into the mass analyser where they are separated according to their mass/charge ratio and finally detected. The result of molecular ionisation, ion separation and ion detection is a spectrum that can provide the molecular mass of the substance(s) present in the sample(s).
A mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio (m/z) of its ion. Ions are generated by inducing either the loss or gain of a charge from a neutral species. Once formed, ions are electrostatically directed into a mass analyser where they are separated according to m/z and finally detected. The result of molecular ionization, ion separation, and ion detection is a spectrum that can provide molecular mass and even structural information.
Determination of accurate mass of an analyte
The service can provide the accurate mass of compounds, both in mixture or as single compound using the latest technology HPLC- Chip- MS-Q-TOF instrument. The Agilent ESI-Q-TOF 6520® is a mass spectrometer coupled with a Agilent nano HPLC Chip Cube® equipped with a double quadrupole and a TOF analyser that allows determination of the exact mass (error less than 2 ppm) of molecules between 200 to 20000 Daltons molecular weight. The possibility to separate complex mixture by nano-HPLC afford the analysis of metabolites or biological fluid to determine their exact mass and hopefully the structure of the molecule. The latest possibility is allowed by the quadrupole ion trap that provide the MS/MS analysis for the determination of the molecular structure or the peptide sequence.
