Abstract：
:An important factor limiting better understanding of the protective role of sIgA at mucosal surfaces is the limited availability of the purified immunoglobulin. Among other things, purified sIgA is needed for use as a standard in measurements of the concentration of this immunoglobulin in mucosal secretions, particularly in mice, where several models of mucosal infections are available. We describe here a simple method by which one can obtain a mean of 3.5 ml of milk per mouse without a breast pump. Immunoblotting studies after native PAGE demonstrated that the milk contained mainly 420 kDa dimeric sIgA and higher polymeric forms of sIgA; only a trace of monomeric IgA was present. Similar immunoblotting studies after SDS-PAGE revealed that a portion of the sIgA was dissociated by this treatment. The 420 kDa sIgA was purified by salt fractionation, gel filtration, and affinity chromatography, and the purity of the final product was demonstrated by immunoblot analysis of biotinylated polypeptides after reduction of biotinylated protein. The concentration of 420 kDa sIgA in whey was measured by densitometry of immunoblot bands, using the purified 420 kDa sIgA as a standard, and found to be 1.0 +/- 0.3 mg/ml.
