Isoelectric focusing of human salivary secretory-IgA.
A method using overlays of 131I-labelled antisera to IgA or SC was developed for the specific detection of s-IgA in unpurified saliva after isoelectric focusing in polyacrylamide gels. The pI range of salivary s-IgA was 4.8-6.5; that of colostral s-IgA was slightly lower (4.5-5.5).
