Recombinant Human Trypsin
英文简称:
Trypsin
中文名称:
重组人胰蛋白酶
背景资料:
Trypsin (EC3.4.21.4) is part of the serine protease family. Trypsin cleaves lysine and arginine at the C-terminal side of the peptide. The hydrolysis rate is slower if an acidic residue is on either sides of the cleavage site and no cleavage occurs if a proline residue is on the carboxyl side of the cleavage site. Trypsin optimum pH is pH-7 to 9. Trypsin will also hydrolyze ester and amide linkages of synthetic derivatives of amino acids such as: benzoyl L-arginine ethyl ester (BAEE), p-toluenesulfonyl- L-arginine methyl ester (TAME), tosyl-L-arginine methyl ester, N-α-benzoyl-L-arginine p-nitroanilide (BAPNA), L-lysyl-p-nitroanilide, and benzoyl-L-tyrosine ethyl ester (BTEE). Serine protease inhibitors that inhibit recombinant trypsin include TLCK (N-p-tosyl-L-lysine chloromethyl ketone), PMSF (phenylmethanesulfonyl fluoride), benzamidine, soybean trypsin inhibitor, and ovomucoid.
产品描述:
Recombinant Human Trypsin-2 is free from any animal and human sources. Recombinant Human Trypsin-2 expressed in E.Coli having a Mw of 24kDa is purified by standard chromatography techniques. Recombinant Human Trypsin-2 is free from foreign enzymes such as carboxypeptidase A & chymotrypsin. Recombinant Human Trypsin-2 is free from protease inhibitors such as PMSF and EDTA.

大肠杆菌中重组表达
溶解建议:
Sterile Filtered lyophilized powder. The protein was lyophilized without 10mM Sodium Acetate buffer and 50mM NaCl. It is recommended to reconstitute the lyophilized Human Trypsin in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
保存建议:
Recombinant Human Trypsin although stable at room temp for 1 week, should be stored desiccated below -18
应用领域:
重组人胰蛋白酶产品可广泛应用于酶活性研究、代谢研究、功能研究、蛋白互作研究、ELISA检测、Western Blot、免疫组化等生物医学研究领域。

文献和实验胰蛋白酶 trypsin 为蛋白酶的一种, EC3.4.21.4。在脊椎动物中,作为消化酶而起作用。在胰脏是作为酶的前体胰蛋白酶原而被合成的。作为胰液的成分而分泌,受肠激酶,或胰蛋白酶的限制分解成为活化胰蛋白酶,是肽链内切酶,它能把多肽链中赖氨酸和精氨酸残基中的羧基侧切断。它不仅起消化酶的作用,而且还能限制分解糜蛋白酶原、羧肽酶原、磷脂酶原等其它酶的前体,起活化作用。是特异性最强的蛋白酶,在决定蛋白质的氨基酸排列中,它成为不可缺少的工具。牛的胰蛋白酶氨基酸残基 223个,分子
胰蛋白酶抑制剂 trypsin inhibitor 由生物产生,为与胰蛋白酶结合具有抑制该酶作用的物质。最初在胰脏中发现,但多数发现于血浆、豆科植物的种子、鸟类的卵等。认为动物的胰蛋白酶抑制剂的作用是调节胰蛋白酶的活性,但植物中的这种物质,其存在的意义还不清楚。它和胰蛋白酶形成 1∶ 1复合体,覆盖着活性部位起抑制作用。一般其结合力相当强,特异性也高,但有的对胰糜蛋白酶等其它蛋白酶也起抑制作用。上述列举的是低分子蛋白质,但最近从放线菌中发现一种新类型的物质,称为白肽
