Background
HLA-E is a nonclassical member of the major histocompatibility complex class I gene locus. HLA-E protein shares a high level of homology with MHC Ia classical proteins: it has similar tertiary structure, associates with ?2-microglobulin, and is able to present peptides to cytotoxic lymphocytes. The main function of HLA-E under normal conditions is to present peptides derived from the leader sequences of classical HLA class I proteins, thus serving for monitoring of expression of these molecules performed by cytotoxic lymphocytes.
Description
Recombinant Human HLA-E*01:03 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-Ile305(HLA-E*01:03),Ile21-Met119(B2M) and VMAPRTLVL peptide.
Target
HLA-E*01:03 Tetramer
Species
Human
Gene/Protein ID
P13747(HLA-E*01:03)&P61769(B2M)&VMAPRTLVL
Exact Sequence
Gly25-Ile305(HLA-E*01:03),Ile21-Met119(B2M)and VMAPRTLVL 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 17.61 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 SEC-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.
