Human secretory IgA is mainly a disulfide-bonded dimer whose polymer conformation is secondarily stabilized by conjugation with one molecule of “secretory piece” (SP). The noncovalent interactions between SP and IgA are highly dependent upon an a

A technique is described for the assessment of local IgA production in external secretions variably contaminated with serum IgA. The combination of total IgA and secretory piece measurements by radial immunodiffusion and 11S and 7S IgA measurements b

Proteins of human cervical mucus were quantified on polyacrylamide gels and their concentrations relative to the mucous glycoprotein were calculated. In contrast with the cyclic variation to be expected in the ratio between albumin and the mucous gly

Human colostral IgA was isolated and characterized for its immunological and physicochemical properties. The colostral IgA has a molecular weight fo 385,000, with a sedimentation coefficient, 11·50 S and a diffusion coefficient, 2·66. Reduction and

The quaternary structure of human secretory immunoglobulin A is stabilized by noncovalent forces to a degree that certain antigenic determinants of the secretory piece subunit are inaccessible. The strength of these noncovalent interactions depends o

Examination of urine from patients who underwent severe exercise has demonstrated that approximately 14% of the γA is present in secretory form whereas the remainder is excreted as 7S serum type γA. In normal urine at least 90% of the γA is excret

SummarySecretory IgA is an immunoglobulin (molecular weight = 400 000) found primarily in secretions. Using a sensitive double-antibody radioimmunoassay, the level of the secretory piece of IgA in amniotic fluid was found to be about 2 μg/ml at 15-2

THE γA class of immunoglobulins is a minor component of the serum immunoglobulins. It is a major, and sometimes the only, immunoglobulin in certain external secretions of man1, rabbits2,3 and dogs4. The γA of human external secretions has a charact
