Product introduction

Recombinant Biotinylated Human Peptide Ready HLA-B*57:01&B2M Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. It contains Gly25-Ala362(HLA-B*57:01) & Ile21-Met119(B2M) (accession: AAA36231.1(HLA-B*57:01) & P61769(B2M)).

Product details

Molecular aliases: MHC; HLA-B*57:01; Peptide Ready
Protein length: Gly25-Ala362
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 48.2 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis 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: Supplied as 0.22 μm filtered solution in PBS, 100mM Arginine (pH 7.4).
Storage: Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Background

HLA-B*57:01&B2M&Peptide ready Monomer is absent from peptide, namely peptide-receptive MHC. It can be loaded with antigenic peptides matching HLA-B*57:01. Peptide ready MHC molecules comprising human HLA alleles and B2M, which can be readily tetramerized and loaded with peptides of choice in a high-throughput manner.
