蛋白結(jié)構(gòu)(Molecular Characterization)
Human ITGA4&ITGB7 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA4 and ITGB7, has a calculated MW of 111.4 kDa (ITGA4) & 83.7 kDa (ITGB7). The protein migrates as 55 kDa, 80 kDa, 100-120 kDa and 130-150 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) 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 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.

Integrin alpha 4 beta 7分子背景
整合素α4β7是一種整合素家族粘附受體,與α4β1(VLA4)和E-鈣粘蛋白受體αEβ7共享亞基。整合素α4β7對腸黏膜歸巢至關(guān)重要,在派爾氏結(jié)或腸系膜淋巴結(jié)的T細(xì)胞活化過程中被誘導(dǎo)。其表達(dá)需要來自局部樹突和基質(zhì)細(xì)胞的信號,包括分泌的視黃酸。HIV-1包膜蛋白gp120與整合素α4β7的活性形式結(jié)合,這可能解釋也可能不解釋腸道相關(guān)淋巴組織(GALT)中HIV-1病毒的濃度。整合素α4β7也可能參與急性腸移植物抗宿主?。?/span>GVHD)中的淋巴細(xì)胞運(yùn)輸。
