The γ-trace concentration of normal human seminal plasma is thirty-six times that of normal human blood plasma

Fresh human seminal plasma was demonstrated to contain a basic microprotein with the same size, electrophoretic mobility, isoelectric point and immunochemical properties as isolated human γ-trace. The concentration of γ-trace in 24 normal seminal plasma samples was found to be (mean ± SD): 51 ± 8.1 mg/l which is 36 times higher than the normal human blood plasma concentration of γ-trace.
