Background
HLA-G is a molecule that was first known to confer protection to the fetus from destruction by the immune system of its mother, thus critically contributing to fetal-maternal tolerance. The first functional finding constituted the basis for HLA-G research and can be summarized as such: HLA-G, membrane-bound or soluble, strongly binds its inhibitory receptors on immune cells (NK, T, B, monocytes/dendritic cells), inhibits the functions of these effectors, and so induces immune inhibition.
Description
Recombinant Biotinylated Human HLA-G Tetramer Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal,tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Thr305(HLA-G),Ile21-Met119(B2M) and RIIPRHLQL peptide.
Target
HLA-G Tetramer
Species
Human
Gene/Protein ID
P17693-1(HLA-G)&P61769(B2M)&RIIPRHLQL
Exact Sequence
Gly25-Thr305(HLA-G),Ile21-Met119(B2M)and RIIPRHLQL peptide
Molecular Weight
The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on the Tris-Bis PAGE result.
Activity
The affinity constant of 4.38 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Tag
C-His-Avi
Express System
Expi293
Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization.
Stability and Storage

Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

Shipping
Shipped at ambient temperature.
Reconstitution

Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
