重组日本血吸虫谷胱甘肽S-转移酶Class-mu 26 kDa Isozyme由大肠杆菌表达系统生产,编码Met1-Lys218的目标基因被表达。蛋白编号: P08515。
别名:Glutathione S-transferase class-mu 26 kDa isozyme; GST 26
表达系统:E.coli
表观分子量:28 KDa,还原条件
纯度:通过还原SDS-PAGE测定,大于95%
内毒素:经LAL测试,小于0.1 ng/µg(1 EU/µg)
存储及稳定性:冻干的蛋白质应储存在<-20°C,尽管在室温下可稳定3周。重组的蛋白质溶液可在4-7°C储存2-7天。重组的样品等分在<-20°C下可稳定3个月。
生物活性:谷胱甘肽S-转移酶(GSTs),以前被称为配体蛋白,包括真核和原核第二阶段代谢同工酶家族,最有名的是它们能够催化谷胱甘肽(GSH)的还原形式与异生物底物的共轭以达到解毒的目的。GST家族由三个超级家族组成:细胞膜、线粒体和微粒体(MAPEG)蛋白。GST同工酶似乎在寄生虫的解毒系统中起着核心作用。其他功能也被怀疑包括在增加寄生虫肠道中血色素的溶解度方面的作用。GSTs的活性取决于来自合成酶γ-谷氨酰半胱氨酸合成酶和谷胱甘肽合成酶的GSH的稳定供应,以及特定转运器的作用,将GSH的共轭物从细胞中移除。GSTs的主要作用是通过催化GSH对所述非极性异生物底物的亲电碳、硫或氮原子的亲核攻击来解毒异生物,从而防止它们与关键的细胞蛋白和核酸相互作用。

Recombinant Human B2M Protein (Mammalian, C-6His)
β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states. |
Recombinant Mouse E-Selectin/CD62E Protein (HEK293)
E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis. |
Recombinant Human DPP4/CD26 (Mammalian, C-6His)
DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. |
Recombinant Human USP14 (E.coli, N-6His)
USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1. |
