Background: 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.
Source: 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
