QUANTITATIVE COMPARISONS OF THE PROTEINS OF THE SEMINAL PLASMAS OF BULL, RAM, RABBIT AND BOAR BY AGAR GEL ELECTROPHORESIS

Abstract

Summary. A quantitative agar gel zone electrophoretic method has been used to establish comparatively at one time and under as similar conditions as possible, the relative amounts and mobilities of the seminal plasma proteins of the bull, ram, boar and rabbit. A striking species specificity was shown in the electrophoretic patterns. The number of components, relative mobilities, glycoprotein and lipoprotein contents and the relative amounts of the protein components varied markedly according to the species. There was little variation between the electrophoretic patterns of seminal plasma collections obtained from five animals in any one species and the variations in pattern between the collections from any one individual animal was also small.
