Human secretory IgA

Purified human secretory IgA may be used as a reference antigen, calibrator, coating protein and blocking agent in a variety of immunoassays including immunodiffusion, immunoelectrophoresis, ELISA, Western blotting, dot-immuno-binding assays (DIBA), haemagglutination, and cell-binding assays.

Confirmed by immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Not less than 98% as determined by agar-gel electrophoresis, quantitative densitometry immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). The ratio of IgA subclasses IgA1 and IgA2 has been determined and found to be 60/40. This secretory IgA contains J chain and secretory component. The product contains a trace of non-Ig protein.

Lyophilized, stable white powder. No preservative added

Lyophilized, stable white powder. No preservative added The lyophilized content is reconstituted by adding 0.5 ml of sterile distilled water, mixed gently by inversion until complete dissolution is obtained.

Human colostrum. The protein is isolated according to a method described in J. Mestecky and M. Kilian, Immunoglobulin A (IgA), in Methods in Enzymology, Vol 116, pp 37-75, 1985
