摘要
为比较不同获能方法对绵羊精子的获能效果,新鲜绵羊精液分别经肝素上游法(swim-up)、钙离子载体(IA,A23187)诱导法、Percoll离心法和Percoll离心后肝素孵育法进行精子获能的诱导后与体外成熟的绵羊卵母细胞进行体外受精,并利用金霉素荧光染色(chlortetracycline,CTC)法结合各自相应的体外受精结果对其获能效果进行检验。结果显示上游法处理后精子的获能比例和受精后的卵裂率均高于其它组,说明肝素上游法可以较好的诱导绵羊精子获能。
In this experiment, the discrepancy was compared among the ＂Swim-up＂ , Induction by A23187, Percoll and Incubation after Percoll methods for ovine sperm capacitation in vitro with chlortetracycline fluorescence （CTC） staining and in vitro fertilization. The results showed that the rates of sperm capacitation and the cleavage treated by Swim-up method were higher than the others. It might be suggested that the Swim-up method is exactly suitable for the application of in vitro fertilization of sheep.
