In this article, we studied some components in giant panda seminal plasma and their relationship with semen characteristics.The protein bands were separated by SDS-PAGE, platelet-activating factor acetylhydrolase activity and glutamic-aspartic aminotransferase activity were detected by ELASE and chymic colorimetry respectively. The results are as followed:Twelve protein bands in giant panda seminal plasma were identified by SDS-PAGE, the molecular weights were 74.9、59.6、 56.2、 54.7、 47.3、 38.2、 30.8、 23.8、 18.4、 16.8、14.0 and 13.4kDa respectively, six of them (74.9, 59.6, 56.2, 47.3, 30.8 and 13.4kDa) werepresent in all samples. However, there was no relationship was found between the abnormalprotein bands appeared in several samples and semen characteristics in our experiment.
