Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the heavy chain of human IgA but not with human IgG or IgM.No antibody was detected against non-immunoglobulin serum proteins.The antibody may cross-react with IgA from other species.
40 nm Colloidal Gold
Colloidal gold conjugates are widely used commercially in lateral flow immunoassays due to their ease of production, conjugate stability and intense optical properties that generate highly sensitive tests with results visible to the naked eye.Conjugates are prepared by passive absorption of the antibody to the gold particle, and are sterile filtered in a low ionic strength buffer containing a preservative.
