产品特性
Identity and purity is confirmed by immunoelectrophoresis and double radial immuno-diffusion (Ouchterlony). Not less than 98 % as determined by agar-gel electrophoresis, quantitative densitometry immunoelectro-phoresis 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.
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-immunobinding assays (DIBA), haemagglutination, and cell-binding assays.
