Fibrinopeptide A human has been used for protein control experiments performed during sandwich ELISA microarray assay to distinguish between plasma and serum fibrinogen samples. It has also been used in a peptide mixture along with BSA (bovine serum albumin) to ascertain the relation between fragmentation voltage and peptide ion drift time for IMS-MS (ion mobility spectrometry coupled with mass spectrometry).
Fibrinogen plays essential roles in coagulation of blood, wound healing, platelet aggregation and has roles in various other physiological processes. Increase in the levels of fibrinopeptide A (FPA) is found in multiple disorders such as coronary artery disease, disseminated intravascular coagulation, arterial thrombosis, deep venous thrombosis and cancers.
