Abstract
Concentrations of total colostral IgA were compared with concentrations remaining after precipitation with antibodies to secretory piece (SP). The anti-SP was obtained by filtering anti-colostral IgA through an immunosorbent column with firmly attached human serum globulins. IgA concentrations were measured by radial immunodiffusion with anti-α-chain serum.
