Fibrinogen gamma prime Polyclonal Antibody – HRP Conjugated
Affinity’s Fibrinogen gamma prime Polyclonal Antibody – HRP Conjugated is the base level of our horseradish peroxidase conjugated Fibrinogen gamma prime antibodies. The purity of IgG is typically 90% and is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v). The titre is essentially the same as the starting antiserum and each vial typically contains the amount of IgG recovered from one milliliter of antiserum however this IgG has been conjugated with Horseradish Peroxidase as an enzyme reporter. This Fibrinogen gamma prime Polyclonal Antibody – HRP Conjugated is generally intended for use as labeled primary antibodies in applications such as immunoassay and immunoblotting.

Description of Fibrinogen
Most of the fibrinogen in the circulation consists of 2 copies of each chain (Aα2, Bβ2, γA2), but in normal plasma approximately 10% of the fibrinogen molecules contain one γA chain and one variant γ chain (termed γ′), in which the c-terminal AGDV residues are replaced with the amino acid sequence VRPEHPAETEYDSLYPEDDL. This variant fibrinogen is commonly referred to as fibrinogen gamma prime (γA/γ′) but has also been called fibrinogen 2 or peak 2 fibrinogen because it elutes separately from fibrinogen 1 (γA2) by ion exchange chromatography. Residues 414-427 of the γ′ chain of fibrin gamma prime (contain a high-affinity binding site for exosite II of thrombin, which allows the active site of bound thrombin to remain available to interact with substrates while demonstrating resistance to heparin mediated inhibition by antithrombin1-4.
