摘要: 背景与目的: 采用FITC标记的无唾液酸胎球蛋白(FITC-ASF)对人精子去唾液酸糖蛋白受体(ASGP-R)进行定位和监测。 材料与方法: 采用FITC标记ASGP-R天然配体无唾液酸胎球蛋白得到FITC-ASF,进一步使用FITC-ASF对人精子表面ASGP-R标记,通过免疫荧光和流式细胞术检测其应用于外源ASF蛋白与该受体结合情况。 结果: FITC-ASF能够较好的标记人精子表面ASGP-R,并成功应用于外源蛋白与该受体的结合。 结论: 本研究为获得一种适合临床广泛应用的新的简便易行的ASGP-R监测方法提供了实验基础。

Abstract: BACKGROUND AND AIM: To locate and monitor Asialoglycoprotein receptor(ASGP-R) on the sperm surface using FITC-labeled asialofetuin(FITC-ASF). MATERIALS AND METHODS: Asialofetuin was labeled with FITC to produce FITC-ASF, which was used in the investigation of binding between foreign protein and ASGP-R on the sperm surface using immunofluorescence and flow cytometry. RESULTS: FITC-ASF was able to label ASGP-R on sperm surface well and successfully applied to assess the binding of foreign protein to the receptor. CONCLUSION: The study provided a new potential and convenient method to monitor ASGP-R.
