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.
Recombinant HLA-G/RIIPRHLQL Tetramer has a calculated mass of approximately 250kDa. Due to glycosylation migrates as an approximately 260 kDa protein under reducing conditions in SDS-PAGE.
purity was determined to be >95% by non reducing PAGE and HPLC (see below methods)
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Recombinant HLA-G/RIIPRHLQL Tetramer was lyophilized from 0.2 µm filtered PBS solution pH7.4
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
