General description

Fibrinogen is a thrombin-coagulable soluble plasma 340 kDa glycoprotein, composed of paired sets of three subunits i.e. α, β, γ. It plays a crucial role in protecting the vascular network against the loss of blood after tissue injury. Among three subunits, β and γ subunits contain one N-glycosylation site, which is occupied by a biantennary N-glycan. It contains three pairs of disulfide-bonded chains called α, β and γ which further folded into four structural domains: the D, E, connector, and the COOH-terminal region of the Aα chain.
The fibrinogen gene cluster consists of fibrinogen α, β and γ chains. It is localized on human chromosome locus 4q31.3−4q32.1.

Specificity

The antiserum has been determined to be immunospecific for fibrinogen by immunoelectrophoresis versus human plasma and fibrinogen.

Immunogen

human fibrinogen

Application

Anti-Fibrinogen antibody is suitable for immunostaining in fibrin deposition analysis of mouse livers and capturing antibodies in the sandwich ELISA. It is also suitable for indirect ELISA at a dilution of 1:10,000 and quantitative precipitin assay at 2.0mg/mL concentration.
Anti-Fibrinogen antibody produced in goat has been used in:
  • western blotting detection in human colon adenocarcinoma cell line
  • detecting fibrinogen in plasma
  • immunoassay of human platelet free plasma (PFP)

Biochem/physiol Actions

Plasmin attacks the Aα chain COOH domain to produce the heterogeneous fragment X. Multiple round of degradation ended with terminal digestion products−fragments D and E which represent the major globular domains in fibrinogen. Mutations in this gene lead to several disorders, including hypofibrinogenemia and afibrinogenemia.

Mn(2+) was found to induce adhesion of HT29-D4 adenoma carcinoma cells to fibrinogen (Fb). This was independent of the expression of the beta3 integrin subunit and involved endogenous alphavbeta6 but not alphavbeta5 integrin. Thus, addition of Mn(2+) led to a...
