对大鼠睾丸和附睾微穿刺标本进行蛋白质分析、微电泳和ABP测定。睾丸网液仅含血清总蛋白浓度的5%。其他生殖道液体含有血液总蛋白浓度的三分之一到一半。从不同的睾丸和附睾区的小管内液体的电泳允许分离的生殖道特异性蛋白质带在每一个研究的液体。来自附睾小管的腔液含有几种血液中没有的蛋白质。雄激素结合活性分析显示睾丸网液中的浓度高于曲细精管液。附睾头液中ABP浓度最高。
Micropuncture samples from rat testis and epididymis were subjected to protein analysis, microelectrophoresis and ABP determinations. Rete testis fluid contained only 5% of the total protein concentration of blood serum. Other reproductive tract fluids contained one-third to one-half the total protein concentrations of blood. Electrophoresis of intratubular fluids from the various testicular and epididymal zones allowed separation of reproductive tract-specific protein bands in each fluid studied. Luminal fluids from the epididymal tubule contained several proteins not appearing in blood. Analysis for androgen binding activity revealed higher concentrations in rete testis fluid than in seminiferous tubule fluid. Caput epididymal fluid contained the highest ABP concentration.
