摘 要:目的筛选用于人凝血因子Ⅸ(human coagulation factorⅨ,FⅨ)干热灭活的保护剂。方法分别将质量分数为1.0%、1.5%和3.0%的甘氨酸、盐酸精氨酸、甘露醇和蔗糖溶液作为保护剂加入同一批次FⅨ半成品,对含不同保护剂的FⅨ半成品进行冻干和于热灭活(100℃处理30min),测定干热灭活前后FⅨ冻干制品的活性。结果干热灭活后,以1.5%盐酸精氨酸作为保护剂的FⅨ冻干制品的活性最高,平均55.5±1.2IU/ml,回收率达100.2%;甘氨酸对FⅨ具有一定的保护作用,含甘氨酸保护剂的FⅨ冻干制品与不含保护剂的FⅨ冻干制品间的活性差异有统计学意义(t=0.442,P=0.002);含甘露醇(t=0.030,P=0.325)或蔗糖(t=-1.120,P=0.532)保护剂的FⅨ冻干制品与不含保护剂的FⅨ冻干制品间的活性差异均无统计学意义。结论1.5%盐酸精氨酸是FⅨ冻干制品干热灭活的理想保护剂。Objective To select a stabilizer for dry-heating inactivation of human coagulation factor Ⅸ (FⅨ). Methods 1.0%, 1.5M and 3.0% glycine, arginine hydrochloride, mannitol and sucrose solutions were added respectively as stabilizers into the same batch of FIX intermediate. FⅨ intermediates with different stabilizers were freeze-dried and dry-heating inactivated(100℃, 30 min). The activity of FⅨ freeze-dryirig product was measured before and after dry-heating inactivation. Results After dry- heating inactivation, the activity of FIX freeze-drying product with 1. 5% arginine hydrochloride as stabilizer was the highest, average 55. 5 + 1.2 IU/ml, and the recovery of FⅨ freeze-drying product reached 100. 2%. Glycine had protection for FⅨ freeze-drying product, and the difference between the activities of F℃ freeze-drying product with glycine as stabilizer and without stabilizer was statistically significant (t=0. 442, P= 0. 002). The activity difference between FIX freeze-drying product with mannitol or sucrose as stabilizer and without stabilizer was not statistically significant (t = 0. 030, P=0.325 for mannitol, and t =- 1. 120, P= 0. 532 for sucrose). Conclusion 1. 5% arginine hydrochloride is lan ideal stabilizer for dry-heating inactivation of FⅨ freeze-drying product.
