寻找一种注射用促肝细胞生长素（ＨＧＦ）适用的辅料。方法：以三批不同批次的ＨＧＦ原料液为实验对象，分别通过 Ｆｏｌｉｎ－酚和~３Ｈ－ＴｄＲ掺入法研究了三种辅料： ３％右旋糖酐， ８％甘露醇， ２％右旋糖酐＋ ８％甘露醇对ＨＧＦ多肽含量及活性的影响。结果：８％甘露醇作为辅料时使ＨＧＦ多肽含量测定显著增高，而右旋糖酐则不影响测定结果。三种辅料对ＨＧＦ活性均无显著影响。结论：最终选用３％右旋糖酐作为ＨＧＦ的辅料。
Looking for a suitable injection of hepatocyte growth factor (HGF) suitable excipients. Methods: Three batches of different HGF feedstocks were used as experimental materials. Three excipients, 3% dextran, 8% mannitol, 2% dextran and 8% Effect of mannitol on the content and activity of HGF polypeptide. Results: HGF peptide content was significantly increased when 8% mannitol was used as an adjuvant, while dextran did not affect the assay results. The three excipients had no significant effect on HGF activity. Conclusion: 3% dextran was finally selected as an excipient for HGF.
