Human DNAM-1 / CD226 Protein, His Tag

DNAX accessory molecule 1 (DNAM-1), a single-pass type I membrane protein, is also known as CD226 antigen and platelet and T cell activation antigen 1 (PTA1), which contains 2 Ig-like C2-type (immunoglobulin-like) domains. DNAM-1 is a ~65 kDa glycoprotein expressed on the surface of natural killer cells, platelets, monocytes and a subset of T cells. DNAM-1 mediates cellular adhesion to other cells bearing its ligands, CD112 and CD155, and cross-linking DNAM-1 with antibodies causes cellular activation. Furthermore, DNAM-1 can interact with PVR and PVRL2.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 27.9 kDa. The protein migrates as 36-50 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 12 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human DNAM-1, His Tag (Cat. No. DN1-H52H6) at 2 μg/mL (100 μL/well) can bind Human CD155, Fc Tag (Cat. No. CD5-H5251) with a linear range of 3-128 ng/mL (QC tested).
