产品介绍
Mca-PLAQAV-Dpa-RSSSR-NH2是用于检测肿瘤坏死因子-α转换酶(TACE或ADAM17)和相关酶(如ADAM8,ADAM9和ADAM10)的荧光肽底物。其N端包含高荧光的7-甲氧基香豆素(MCA)荧光团,可通过荧光共振能量转移(Dark FRET)通过Dpa上的非荧光2,4-二硝基苯基有效地淬灭。它可用于测量能够裂解荧光基团和淬灭基团之间酰胺键的肽酶活性,从而增加荧光强度。该肽序列衍生自促肿瘤坏死因子-α(TNF-α)。 TACE / ADAM17和ADAM10的切割位点是A(Ala)和V(Val)残基之间的肽键。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的荧光底物Mca-PLAQAV-Dpa-RSSSR-NH2。
