【摘要】：目的:建立重組人促卵泡激素(rhFSH)N端不均一性的分析方法,并對不同企業(yè)樣品rh FSH原液的N端不均一性進行比對研究。方法:通過對亞基的還原與烷基化處理方法、糖苷酶切條件及RP-HPLC條件的優(yōu)化,將完整與N端缺失氨基酸的亞基有效分離,建立了2種rhFSH的N端不均一性分析方法,并利用質譜分別對目的蛋白進行定性鑒別。以國內外企業(yè)的rhFSH原液為樣品進行N末端不均一性比較。結果:建立的2種RP-HPLC方法均可實現(xiàn)完整與缺失β亞基的有效分離,各樣品rhFSH的N端不均一性基本一致。結論:rhFSH國內生物類似藥與國外參照藥的N端不均一性比較有較高的相似性;本實驗建立的2種RP-HPLC方法可評價產品質量,為生物類似藥的可比性研究提供技術支持。
[Abstract]:Aim: to establish a method for the analysis of N-terminal heterogeneity of recombinant human follicle stimulating hormone (rhFSH), and to compare the N-terminal heterogeneity of rh FSH samples from different enterprises. Methods: through the reduction and alkylation of subunits, the optimization of the conditions of glucosidase digestion and RP-HPLC, the complete and N-terminal missing amino acid subunits were effectively separated, and two N-terminal heterogeneity analysis methods of rhFSH were established. The target protein was identified qualitatively by mass spectrometry. The N-terminal heterogeneity of rhFSH solution from domestic and foreign enterprises was compared. Results: the complete and missing 尾 subunits were effectively separated by the two RP-HPLC methods, and the N-terminal heterogeneity of rhFSH was basically the same. Conclusion the N-terminal heterogeneity of biological analogues in China is similar to that in foreign countries, and the two RP-HPLC methods established in this experiment can evaluate the product quality and provide technical support for the study of the comparability of biological analogues.
