蛋白结构（Molecular Characterization）
Human ITGAX&ITGB2 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAX and ITGB2, has a calculated MW of 126.5 kDa (ITGAX) and 80.2 kDa (ITGB2). Subunit ITGAX 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 145 kDa (ITGAX) and 90 kDa (ITGB2) under reducing (R) 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）
The integrin αXβ2 takes a key role in host defense and functions as a receptor for the complement C3 cleavage product iC3b, fibrinogen, denatured proteins, and intercellular adhesion molecule (ICAM)-1. Integrin αXβ2 αXβ2 has a unique cellular distribution with expression on monocytes, macrophages, and the CD8− subsets of dendritic cells and involves in priming and regulation of the immune response.
