Recombinant Human HLA-E protein, His-Avi-tagged, Biotinylated

• Cat.No.: HLA-E-039H
• Product Overview: Biotinylated Recombinant Human HLA-E Complex Protein(P61769&P13747&VMAPRTLVL) is expressed from HEK293 with His and Avi tag at the C-terminal. It contains Gly25-Ile305(HLA-E),Ile21-Met119(B2M) and VMAPRTLVL peptide.

Specification

• Description: 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 β2-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.
• Source: HEK293
• Species: Human
• Tag: His-Avi
• Form: Supplied as 0.22um filtered solution in PBS (pH 7.4).
• Molecular Mass: The protein has a predicted MW of 50.2 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on Tris-Bis PAGE result.
• Protein length: It contains Gly25-Ile305(HLA-E),Ile21-Met119(B2M) and VMAPRTLVL peptide.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE
  > 95% as determined by SEC-HPLC
• Storage: The product should be stored at -70°C. Please do not repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
