标记:Unconjugated
蛋白结构(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.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(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是一种整合素家族粘附受体,与α4β1(VLA4)和E-钙粘蛋白受体αEβ7共享亚基。整合素α4β7对肠黏膜归巢至关重要,在派尔氏结或肠系膜淋巴结的T细胞活化过程中被诱导。其表达需要来自局部树突和基质细胞的信号,包括分泌的视黄酸。HIV-1包膜蛋白gp120与整合素α4β7的活性形式结合,这可能解释也可能不解释肠道相关淋巴组织(GALT)中HIV-1病毒的浓度。整合素α4β7也可能参与急性肠移植物抗宿主病(GVHD)中的淋巴细胞运输。
