Product introduction

Recombinant Human HLA-A*24:02&B2M&MAGE-A3 (IMPKAGLLI) 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*24:02), Ile21-Met119(B2M)and IMPKAGLLI peptide (accession: AAA59600.1(HLA-A*24:02) & P61769(B2M) &IMPKAGLLI).

Product details

Molecular aliases: Melanoma-associated antigen 3; MZ2-D; MZ2D; MZ2-D; CT1.3; MAGE-3; HLA-A*24:02; HLA-A2402
Protein length: Gly25-Thr305
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reduced (N) condition based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin: Less than 1 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
