Recombinant Human Peptide Ready HLA-E*01:03&B2M Monomer-Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Gly25-Ile305(HLA-E*01:03) and Ile21-Met119(B2M). HLA-E*01:03&B2M&Peptide ready Monomer is absent from peptide, namely peptide-receptive MHC. It can be loaded with antigenic peptides matching HLA-E*01:03. 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.
