分子别名(Synonym)
Integrin alpha L beta 2,ITGAL&ITGB2
表达区间及表达系统(Source)
Human ITGAL&ITGB2 Heterodimer Protein, His Tag&Tag Free (IT2-H53W3) is expressed from CHO cells. It contains AA Tyr 26 - Met 1089 (ITGAL) & Gln 23 - Asn 700 (ITGB2) (Accession # P20701-1 (ITGAL) & P05107-1 (ITGB2)).
Predicted N-terminus: Tyr 26 (ITGAL) & Gln 23 (ITGB2)
蛋白结构(Molecular Characterization)

Human ITGAL&ITGB2 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAL and ITGB2, has a calculated MW of 124.1 kDa (ITGAL) & 80.2 kDa (ITGB2). Subunit ITGAL is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB2 contains no tag but a basic tail at the C-terminus. The protein migrates as 140-150 kDa (ITGAL) and 90-95 kDa (ITGB2) 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)
>95% 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α-Lβ-2是ICAM1、ICAM2、ICAM3和ICAM4的受体。整合素αLβ2也是F11R的受体(通过相似性)。参与多种免疫现象,包括白细胞-内皮细胞相互作用、细胞毒性T细胞介导的杀伤以及粒细胞和单核细胞的抗体依赖性杀伤。有助于自然杀伤细胞的细胞毒性。参与白细胞粘附和白细胞(包括T细胞和中性粒细胞)的迁移。骨髓中常见淋巴祖细胞的产生所必需的,表明其在淋巴生成中的作用。整合素αLβ2与ICAM3相关,有助于巨噬细胞吞噬凋亡的中性粒细胞。
