Rabbit Fibrinogen Polyclonal Antibody – Affinity Purified
Affinity’s Rabbit Fibrinogen Polyclonal Antibody – Affinity Purified is the highest level of our Fibrinogen antibody family. During the Antigen Affinity Purification process the IgG has had any non-specific immunoglobulin fraction eliminated which enriches the specificity of the remaining immunoglobulin towards the target antigen. The result is a very high-purity product with a substantially higher titre than whole or purified IgG. Our Rabbit Fibrinogen Polyclonal Antibody – Affinity Purified is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v) and is intended for applications such as immunoblotting, immunostaining of cells and several types of immunoassays where the higher signal-to-noise ratio achieved with this enriched product is required.

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.
