天龙抗肿瘤小分子肽纯化工艺
摘要
目的:纯化天龙酶解液
制备小分子肽。方法:用石蜡萃取法除油脂
用Sephadex G-15除氨基酸和盐。结果:天龙酶解液中加入药材质量分数40%的石蜡
加热使完全融化
搅拌
冷藏(6℃)静置4 h
弃去石蜡
水液以每2 mL加于Sephadex G-15柱(1.6 cm×64 cm)上
用去离子水2 mL.min-1洗脱
收集第60~84 mL洗脱液。结论:所筛选的纯化工艺简便可行。
Abstract
Objective:To purify enzymolysis liquid of Gecko
prepared small peptide.Method:Paraffin extraction was used to remove gease
and Sephadex G-15 was adopted to except AA and salts.Result:Added 40% paraffin into enzymolysis liquid of Gecko
melted it
stirred
stilled 4 h at 6 ℃
discarded paraffin
the remaining water solution was added onto Sephadex G-15(1.6 cm×64 cm) every 2 mL
eluted with deionized water by 2 mL·min-1
collected eluate after 60 mL and stopped at 84 mL.Conclusion:The selected purification technology was simple and feasible.
