The leukocyte immunoglobulin-like receptors (LILR) comprise a family of activating and inhibitory type immunoreceptors whose genes are located in the same locus that encodes killer cell Ig-like receptors (KIRs). Human LILRA5, also known as ILT11, LIR-9, and CD85f, consists of a 227 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 10 aa cytoplasmic tail. The ECD contains two Ig-like domains, and the transmembrane segment contains a positively charged aspartic acid residue which may mediate its association with the signaling molecule, FcR common gamma chain . Alternative splicing generates additional isoforms with a 12 aa deletion within the signal peptide and/or a 27 aa substitution for the C-terminal 61 residues. This substitution encompasses both the transmembrane and cytoplasmic regions. LILRA5 is expressed by monocytes, macrophages, and neutrophils. It is found as an approximately 40 kDa molecule on the cell surface, while a soluble 25 kDa form can be released into the synovial fluid of rheumatoid arthritis patients. Cross-linking of LILRA5 on monocytes induces the expression of pro-inflammatory cytokines (IL-1 beta, IL-6, TNF-alpha) as well as the anti-inflammatory IL-10.

表达区间及表达系统 |
Recombinant Human LILRA5/CD85f/ILT11 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Gly42-Arg268. |
分子量 |
Approximately 28.2 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Tris-Bis PAGE result. |
纯度 |
> 95% as determined by SDS-PAGE and HPLC. |
内毒素 |
< 1.0 EU per 1μg of the protein by the LAL method. |
制剂 |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
复溶 |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
运输与保存方法
冰袋运输。-20℃至-80℃保存,一年有效期。
复溶后,-20 至 -80°C,在未开封状态下保存 3-6 个月。复溶后,2-8°C 保存 2-7 天。
