Name : Human HLA-A*02:01&B2M&LMP2 (CLGGLLTMV) Tetramer Protein
Product Source :
Recombinant Human HLA-A*02:01&B2M&LMP2 (CLGGLLTMV) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus,tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Thr305 (HLA-A*02:01), Ile21-Met119 (B2M) and CLGGLLTMV peptide.[Accession | A0A140T913(HLA-A*02:01)&P61769(B2M)&CLGGLLTMV]
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 Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human HLA-A*02:01&B2M&LMP2 (CLGGLLTMV) Tetramer on Tris-Bis PAGE under Non reducing (N) condition. The purity is greater than 95%. SEC-HPLC The purity of Human HLA-A*02:01&B2M&LMP2 (CLGGLLTMV) Tetramer was greater than 95% as determined by SEC-HPLC.

Dose response curve for Anti-HLA-A*02:01&B2M&LMP2 (CLGGLLTMV) Antibody, hFc Tag with the EC50 of 5.0ng/ml determined by ELISA.
Background :
The immunoproteasome, having been linked to neurodegenerative diseases and hematological cancers, has been shown to play an important role in MHC class I antigen presentation. The development of molecular probes that selectively inhibit the major catalytic subunit, LMP2, of the immunoproteasome,LMP2-rich cancer cells compared to LMP2-deficient cancer cells are more sensitive to growth inhibition by the LMP2-specific inhibitor, implicating an important role of LMP2 in regulating cell growth of malignant tumors that highly express LMP2.
Synonyms :
