Immunoglobulin A (IgA) from Normal Human Plasma

Cat. No.: np001084

GRADE & PURITY BioReagent, Native, ≥95%(SDS-PAGE), Protein concentration: See COA

Accession #

P01876,P01877

Overview

IgA is the most abundant immunoglobulin in body fluids and the second most abundant immunoglobulin in plasma, found at a concentration of 0.4 to 2.2 mg/ml. It plays a very important role in the first specific defense against natural infection. Secretory IgA differs from serum IgA in that it contains two additional peptides: the secretory component and the J chain.

Important: IEP shows no reaction with antisera to human IgG, IgM, IgD, and IgE.

Prepared from plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
