title: [Placental-spermatic beta 2-globulin: its immunochemical identification, physicochemical characteristics and localization in the reproductive system].
abstract: A new antigen with beta 2-globulin mobility and M. W. of 20 kD, named placenta-sperm beta-globulin (PSBG), was identified in human early placental tissue. Using immunodiffusion method, PSBG was found in the seminal plasma with the concentration about 120 mg/l, in the amniotic fluid 1-5 mg/l, in the liquor 1-10 mg/l, and also in fetal kidney and stomach extracts. The examination of the male reproductive system revealed PSBG levels in the extracts of adults and fetus.
