Human TRGC2 Protein, His Tag

分子別名（Synonym）

TRGC2

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human TRGC2, His Tag (TG2-H52H3) is expressed from human 293 cells (HEK293). It contains AA Asp 1 - Ala 154 (Accession # P03986-1).

Predicted N-terminus: Asp 1

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 19.5 kDa. The protein migrates as 30-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>90% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）

跨膜蛋白TCR由兩條二硫鍵連接的多肽鏈組成：α和β鏈，γ和δ鏈。每條多肽鏈由一個(gè)可變區(qū)和一個(gè)恒定區(qū)組成。TRGC2是T細(xì)胞受體（TCR）γ鏈的恒定區(qū)。它識別上皮邊界經(jīng)常表達(dá)的非肽抗原，這意味著激活γδT細(xì)胞的抗原大多是MHC非依賴性的。γδT細(xì)胞在人類和小鼠中具有廣泛的功能，包括皮膚和粘膜上皮傷口修復(fù)、耐受誘導(dǎo)、細(xì)胞毒性和調(diào)節(jié)免疫反應(yīng)的各種細(xì)胞因子的產(chǎn)生。
