DNA sequence encoding the Human (HLA-G AA25-305 [accession P17693] and the B2M protein AA2-119 [accession P61769], fused to the RIIPRHLQL peptide.This complex includes a C terminal polyHis AVI tag and was expressed in HEK cells, The tetramer conformation was achieved through biotinylation of the monomer and then covalently binding the monomers via an avidin biotin reaction.
