HLA-DRB1 protein, as the beta chain of MHCII, guides T cell recognition, orchestrates immune responses against pathogens and tumors, and adapts its antigen presentation in the tumor microenvironment, ensuring a diverse role in immune responses and tolerance mechanisms, notably influenced by specific alleles like DRB1*01:01. HLA-DRB1 Protein, Human (Myc, His-SUMO) is the recombinant human-derived HLA-DRB1 protein, expressed by E. coli , with N-His, C-Myc, N-SUMO labeled tag.
