Description

Application

[Glu¹]-Fibrinopeptide B human has been used:

• during LC-MS to avoid cross-contamination and to analyze the performance of mass spectrometer and LC-instrument[1]
• for two-point calibration during 2D (dimensional) gel electrophoresis and protein identification by mass spectrometry of histidine (his)-Pup (prokaryotic ubiquitin-like protein) isolated from Mycobacterium smegmatis[2]
• for two-point calibration during one-dimensional gel electrophoresis and tandem mass spectrometry (MS) for the characterization of soluble protein sample obtained from the salivary gland homogenates of Cimex lectularius[3]
• as a standard for the correction of mass drift in data obtained from MS and MS/MS performed on peptides obtained from trypsin-digestion of protein disulfide isomerase (PDI)[4]

Biochem/physiol Actions

Fibrin formation is an essential part in wound healing and inflammation. Fibrinopeptide B (FPB) can also cause chemotactic migration of neutrophils, without the simultaneous release of lysosome enzymes.[5] It is produced during the coagulation of fibrinogen, which is essential for physiological homeostasis. It is involved in various disorders such as thrombosis and disseminated intravascular coagulation.[6]

General description

Fibrinopeptide B (FPB) is produced during the cleavage of fibrinogen, by thrombin, to fibrin monomer. It is cleaved off from the N-terminal of the fibrinogen β chain.[5] This peptide is composed of 14 amino acids.[6]
