title: Spermatozoal hapten gained via autolysis.
abstract: Using autolysis different spermatozoa surface peptides were solubilized. The resulting low molecular weight compounds were further separated by gel-chromatography on Biogel P-4, thin-layer chromatography on Cel 400 and thin-layer-electrophoresis. After the conjugation of the compound with cytochrome C a conformation-independent determinant was detected with immuno-electrophoresis. Out of the 17 fractions tested only fraction 3, with a molecular weight of 1800 daltons revealed a precipitation reaction with human sperm-immobilizing sera and rabbit antihuman sperm-serum. All 17 fractions showed no precipitation reaction against human sperm-agglutinating sera.
