Abstract

Some differences in the distribution of lectin-binding sites on the surface of the plasma membrane of acrosomal and postacrosomal regions and tail of ejaculated human spermatozoa were demonstrated by means of horseradish peroxidase labeled soybean agglutinin. The acrosomal region was more densely coated with labeled lectin in comparison with the postacrosomal region. Hapten inhibition with N-acetyl-D-galactosamine was used as control.

人类精子表面的大豆凝集素结合位点
通过辣根过氧化物酶标记的大豆凝集素,证明了人类射精精子顶体区、后顶体区和尾部质膜表面凝集素结合位点分布的一些差异。与顶体区相比,顶体区被标记凝集素涂布的密度更大。用 N-乙酰-D-半乳糖胺抑制合粒作为对照。
