Recombinant Human HLA-A*02:03&B2M&AFP (FMNKFIYEI) Tetramer Protein is expressed from HEK293 His tag and Avi tag at the C-Terminus, tetramer is assembled by biotinylated monomer and streptavidin.It contains Gly25-Thr305(HLA-A*02:03),Ile21-Met119(B2M) and FMNKFIYEI peptide. Alpha-fetoprotein (AFP), a specific liver cancer marker, T cells expressing AFP-CAR selectively degranulated, released cytokines, and lysed liver cancer cells that were HLA-A*02:01 /AFP while sparing cells from multiple tissue types that were negative for either expressed proteins.CAR T-cell immunotherapy targeting intracellular/secreted solid tumor antigens can elicit a potent antitumor response.
