The difference between semen and seminal plasma immunoreactive human prolactin (iPRL) correlates with sperm count. Seminal plasma separated from sperm before freezing (SPB), after freezing (SPA), and serum were fractionated by G100 Sephadex chromatography. SPA contained four different molecular weight fractions of iPRL. Each fraction contained approximately 25% of the total iPRL measured. SPB and serum each had three molecular weight fractions and most of the iPRL coeluted with monomeric 125I-hPRL.
精液与精浆免疫反应性人催乳素（iPRL）之间的差异与精子计数相关。在冷冻前（SPB）、冷冻后（SPA）从精子中分离出的精浆以及血清通过G100葡聚糖凝胶色谱法进行分级分离。SPA含有四种不同分子量的iPRL组分。每个组分约占所测iPRL总量的25%。SPB和血清各有三个分子量组分，且大部分iPRL与单体125I-hPRL共洗脱。
