Fibrinopeptide A, human TFA()CAT: I016739) is a synthetic peptide corresponding to the N-terminal fragment released from the α-chain of fibrinogen during thrombin-mediated cleavage. It plays a key role in blood coagulation by initiating fibrin polymerization and clot formation. As a research reagent, Fibrinopeptide A serves as a standard in coagulation studies, mass spectrometry calibration, and peptide mapping. It is widely used to investigate thrombin activity, fibrinogen processing, and platelet function. The trifluoroacetate (TFA) salt form enhances peptide stability and handling. This peptide provides a reliable tool for studies in hematology, cardiovascular research, proteomics, and biomarker discovery.
