Abstract
The secretory immune systems of the cow and sheep were found to be strikingly similar. The principal immunoglobulin in the saliva and colostrum of both species is a “fast” 7 S γ G1 protein which is low in carbohydrate. Although suggestive evidence was obtained for a 10 S secretory immunoglobulin, proof of its existence must await isolation and complete separation from the major 7 S γ G1 component. The secretory 7 S γ G1 is immunologically identical to the γ G1 of serum and in this study no evidence of a component analogous to the human secretory “piece” was detected.Keywords
