Female mice serum and vaginal secretion antibodies , their fertility and the pathological changes were determined . on the other hand , the effects of the anti - serum against synthetic peptide on the sperm - egg interaction during ivf and the location of p3 peptide in sperm were watched . the main results and conclusions were as follows : 1 ) the new antigen p3 peptide which harvested from the 430a peptide synthesizer were verified by the mass spectrograph and hplc , that the ratio of mass / charge of the synthetic peptide was equal to the molecular weight in theory and its purity was above 95 % 本研究的主要結果和結論如下:一、經抗原分子設計,在430a自動肽合成儀上合成的新抗原p3 ,經質譜儀分析證明其荷質比與理論一致;純化后,其純度大于95 ;將新抗原與klh偶連后免疫小鼠,經westernblot證實其誘導的特異性抗體可識別小鼠、大鼠、人睪丸組織中分子量約為22kd和55kd左右的蛋白質。

Single - focusing mass spectrograph 單聚焦質譜儀

In the mass spectrograph the ions are focused onto a photographic plate . 在質譜儀中,離子聚焦在感光板上。
