Product information "Fibrinogen, Mouse (Coagulation Factor I)"
The thrombin (IIa) catalyzed cleavage of soluble fibrinogen (Fbg) to form fibrin (Fbn) is the terminal proteolytic event in the coagulation cascade. These soluble Fbn monomers spontaneously polymerize to form an insoluble Fbn network which is stabilized by the factor XIIIa catalyzed crosslinking of lys and glu residues of a and g chains. This Fbn network is the major protein component of the hemostatic plug. Plasma fibrinogen is large glycoprotein (40kD) synthesized in the liver and circulating at a concentration of 2.6mg/ml. It is a disulfide linked dimer composed of 3 pairs of disulfide linked non-identical polypeptide chains (Aa, Bb and g). Notable features of the Aa chain are the N-terminal peptide (fibrinopeptide A (FPA, 1-16)), factor XIIIa crosslinking sites and 2 phosphorylation sites. When synthesized, Fbg is fully phosphorylated, but circulates at only 20-30% phosphorylation. The Bb chain contains fibrinopeptide B (FPB, 1-14), one of the 3 N-linked carbohydrate moieties (Mr%00) and an N-terminal pyroglutamic acid. The g chain contains the other N-linked glycosylation site and a factor XIIIa crosslinking sites. The 2 elongated subunits ((AaBbg)2) are aligned in an antiparallel manner forming a trinodular arrangement of the six chains. The nodes are formed by disulfide rings between the 3 parallel chains. The central node (n-disulfide knot, E domain) is formed by the N-termini of all six chains held together by 11 disulfide bonds. This region contains the 2 IIa-sensitive sites. The release of FPA by cleavage at R16-G17 generates Fbn I, exposing a polymerization site (17-20) on the Aa chain. These regions bind to complimentary regions on the D domain of Fbn to form protofibrils. Subsequent IIa cleavage of FPB (R14-G15) from the Bb chain exposes additional polymerization sites and promotes lateral growth of the Fbn network. , Source:, Mouse Fibrinogen, from plasma. Coagulability: ~85% (homogenous on 4-20% SDS-PAGE gels). Storage and Stability: For long-term storage, aliquot to avoid repeated freezing and thawing and freeze at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Aliquots are stable for 6 months.
