胃蛋白酶和其他蛋白水解酶用于各种蛋白的实验室分析。胃蛋白酶和木瓜蛋白酶通常用于生成抗体片段。木瓜蛋白酶用于将抗体裂解成含有单个抗原结合结构域的 Fab 片段。胃蛋白酶通过仅去除铰链区以外的 Fc 结构域部分产生 F(ab')2 片段。生成的 F(ab')2 片段包括两个由铰链区二硫化物结合的抗体结合 Fab 片段。
What is the best enzyme to use for protein digestion for mass spectrometry samples?
Trypsin (Cat. Nos. 90057, 90058) or Trypsin/LysC mix (Cat. Nos. A40007, A40009, A41007) are most commonly used for proteomic applications in order to ensure reproducibility and complete digestion. Other commonly used enzymes for purified protein characterization and unique applications include Chymotrypsin Protease, MS Grade (Cat. No. 90056), Immobilized Pepsin (Cat. No. 20343), LysN Protease, MS Grade (Cat. No. 90300), Asp-N Protease, MS Grade (Cat. No. 90053), and Glu-C Protease, MS Grade (Cat. No. 90054).
