Abstract

PURPOSE

Early pregnancy factor (EPF)-like activity from culture supernatants obtained from stimulated lymphocytes of pregnant women was characterized and identified.

METHODS

The enzyme-linked immunosorbent assay depending on the presence of "Fc" receptors on bovine spermatozoa was used to identify the EPF-like molecule purified by gel filtration and reverse-phase high-performance liquid chromatography.

RESULTS

The results indicated that the crude lymphocyte culture supernatant, the EPF-positive G IV fraction obtained on gel filtration, and the EPF-positive reverse-phase high-performance liquid chromatography protein readily bound with the different concentrations of aggregated human gamma-globulin in a manner similar to that in which the standard control of aggregated human gamma-globulin binds to the bovine spermatozoa.

CONCLUSIONS

EPF-like activity synthesized and secreted by lymphocytes during pregnancy may be a Fc-receptor-like molecule.

摘要

目的

对从孕妇刺激淋巴细胞获得的培养上清液中的早期妊娠因子(EPF)样活性进行表征和鉴定。

方法

采用基于牛精子上“Fc”受体存在的酶联免疫吸附测定法,鉴定通过凝胶过滤和反相高效液相色谱法纯化的EPF样分子。

结果

结果表明,粗淋巴细胞培养上清液、凝胶过滤获得的EPF阳性G IV级分以及EPF阳性反相高效液相色谱蛋白,能以类似于人聚合γ球蛋白标准对照与牛精子结合的方式,与不同浓度的人聚合γ球蛋白结合。

结论

妊娠期间淋巴细胞合成和分泌的EPF样活性可能是一种Fc受体样分子。
