Product overview

Recombinant PE-Labeled Human Peptide Ready HLA-B*27:05&B2M Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. PE-Labeled Human Peptide Ready HLA-B*27:05&B2M Tetramer is assembled by biotinylated monomer and PE-Labeled streptavidin. It contains Gly25-Thr305 (HLA-B*27:05) and Ile21-Met119 (B2M) (accession: AAA36221.1(HLA-B*27:05) & P61769(B2M)).

Background

HLA-B*27:05&B2M&Peptide ready Monomer is absent from peptide, namely peptide-receptive MHC. It can be loaded with antigenic peptides matching HLA-B*27:05. 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.
