Native Human IgG FC fragment protein is a Full Length protein, expressed in Native, with >95% purity and suitable for SDS-PAGE.
pH: 8
Preservative: 0.05% Sodium azide
Constituents: 1.16% Sodium chloride, 0.79% Tris HCl
Protein Determination: Extinction Coefficient (E) 0.1% at 280nm =1.46.
IgG is cleaved using Papain to product the Fc fragment. The IgG fc fragment does not bind antigen; however, it does contain the classic antigenic determinants and biological activity with respect to cytotrophic reactions, binding of complement and catabolic rate control.
Shown to be non reactive for HbsAG, anti-HCV, anti-HBc, and negative for anti-HIV 1 and 2 by FDA approved tests.
