title: [Immunochemical identification and physico-chemical characteristics of specific proteins of seminal plasma].
abstract: Two specific antigens of human spermatic plasma have been identified: thermostable alpha 1-globulin and alpha 2-microglobulin of fertility. The thermostable alpha 1-globulin presents a glycoprotein containing sialic acids with a molecular weight of 60000 +/- 7000. In addition to the sperm, it has been also identified in the saliva of men and women. Alpha 2-microglobulin of fertility is identical to placental alpha 2-microglobulin. This protein is specific for the reproductive system of men and women. The physicochemical properties of the test antigens are described.
