Human CD226 antigen also known as DNAX accessory molecule 1 (DNAM-1), GenBank Accession No. NM_006566, a.a. 19-247 fused to Fc region of human IgG1, this protein is enzymatically biotinylated using AviTag technology and expressed in a HEK293 cell expression system. MW = 54.7 kDa (monomer). This protein runs at a higher MW by SDS-PAGE due to glycosylation.

Notes
CD226, biotin binding to CD155, His-tag was confirmed according to the protocol for BPS Cat. 72052. Briefly, 6 ng of CD226-biotin was mixed with varying amounts of CD155, His-tag in CD226 assay buffer at a final volume of 10 ul and allowed to incubate for 1 hr at room temp. Nickle acceptor beads were added for 30 min, followed by Strep-conjugated acceptor beads for 30 min and reading alpha-counts.
The aggregation state of this product has been confirmed to be<10%. Avoid freeze/thaw cycles. Protein may be diluted to>=100 ug/ml in PBS + glycerol and stored at -80°C.
