表达区间及表达系统(Source)
Mouse ITGAE&ITGB7 Heterodimer Protein, His Tag&Tag Free (IT7-M53W3) is expressed from CHO cells. It contains AA Phe 20- Val 1114 & Glu 20 - Arg 724 (Accession # Q60677 & P26011).
Predicted N-terminus: Phe 20 & Glu 20
蛋白结构(Molecular Characterization)

Mouse ITGAE&ITGB7 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAE and ITGB7, has a calculated MW of 127.5 kDa (ITGAE) and 81.6 kDa (ITGB7). Subunit ITGAE is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB7 contains no tag but a basic tail at the C-terminus. The protein migrates as 90-95 kDa,130 kDa and 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.

背景(Background)
整合素αEβ7由两个主要亚基组成:整合素αE(ITGAE)也称为CD103(分化簇103),整合素β7是一种整合素蛋白,在人类中由ITGB7基因编码。整合素αEβ7(CD103)主要由粘膜组织内的T淋巴细胞谱系细胞表达。与其他整合素相比,这是一种非常狭窄的表达模式。表达α-E-β7的淋巴细胞在肠道中很丰富,占身体总T细胞补体的主要部分。
肺移植的有效性因相对较高的排斥反应发生率而受到损害。肺通常含有大量与气道上皮接触的淋巴细胞,其中一部分表达粘膜整合素α(E)(CD103)β(7)。这种整合素不是归巢受体,但被认为可以将淋巴细胞保留在上皮表面。
