Equine serum and secretions were found to contain a protein which cross-reacted with an antiserum against human IgA, but not with antisera against any other human immunoglobulin. The physicochemical properties of equine IgA resembled those of human IgA. IgA was found to be the immunoglobulin having the highest secretion serum concentration ratio in equine lacteal and salivary secretions, and to be the protein produced by the majority of immunoglobulin-containing cells in the of the equine intestine.
马血清和分泌物中发现含有一种蛋白质,它能与抗人IgA抗血清发生交叉反应,但不与抗任何其他人类免疫球蛋白的抗血清发生反应。马IgA的理化性质与人IgA相似。在马的乳糜和唾液分泌物中,IgA是分泌/血清浓度比最高的免疫球蛋白,并且是马肠道中大多数含免疫球蛋白细胞产生的蛋白质。
