Wako 125-05061 赖氨酰肽链内切酶 20 ug×5

赖氨酰肽链内切酶是质谱分析前处理时最常用的蛋白分解酶即赖氨酰肽链内切酶，赖氨酰肽链内切酶可以特异性切除赖氨酸基团C 末端的多肽，赖氨酰肽链内切酶可用于蛋白测序分析和Lys-X 化合物的酶合成。
若同时使用赖氨酰肽链内切酶和胰酶，可更好地切断赖氨酸基团的多肽，增加多肽的数量。赖氨酰肽链内切酶已按照使用习惯做成小包装，是方便使用赖氨酰肽链内切酶的冷冻干燥品。
【产品特点】
赖氨酰肽链内切酶Lysyl Endopeptidase 125-05061 wako
1）赖氨酰肽链内切酶用于蛋白质谱分析：高特异性、高蛋白质消化率；
2）赖氨酰肽链内切酶能增加肽段数量、提高裂解效率；
3）赖氨酰肽链内切酶独立包装，20 μg/一支
【结果】表明Lep 酶解的错误裂解率最低。
Tp 酶解时加入Lep 后，错误裂解率有所降低，同时，赖氨酰肽链内切酶可以鉴定出更多的多肽。

	Tp	Lep	Lep +Tp
裂解位点	精氨酸和赖氨酸的C 端	赖氨酸的C端	精氨酸和赖氨酸的C端
错误裂解率( 错误裂解所占比例)	多(8 %)	很少(0 %)	少(3 %)
鉴定出的多肽数量	17	19	22
