Recombinant Human DNAM-1/CD226 Fc Chimera (Catalog # 666-DN) under non-reducing conditions only
0.25 µg/106 cells
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
Measured by its ability to neutralize DNAM-1/CD226-mediated adhesion of the COLO 205 human colorectal adenocarcinoma cell line. Cosman, D. et al. (1997) Immunity 7:273. The Neutralization Dose (ND50) is typically 0.1‑0.6 µg/mL in the presence of 20 µg/mL Recombinant Human DNAM-1/CD226 Fc Chimera.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Detection of DNAM-1/CD226 in Human PBMCs by Flow Cytometry.
Human peripheral blood mononuclear cells (PBMCs) gated on CD3- cells were stained with Mouse Anti-Human NCAM‑1/CD56 APC‑conjugated Monoclonal Antibody (Catalog # FAB2408A) and either (A) Mouse Anti-Human DNAM-1/CD226 Monoclonal Antibody (Catalog # MAB666) or (B) Mouse IgG1 Isotype Control (Catalog # MAB002) followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).
Cell Adhesion Mediated by DNAM-1/CD226 and Neutralization by Human DNAM-1/CD226 Antibody.
Recombinant Human DNAM-1/CD226 Fc Chimera (Catalog # 666-DN), immobilized onto a microplate, supports the adhesion of the COLO 205 human colorectal adenocarcinoma cell line in a dose-dependent manner (orange line). Adhesion elicited by Recombinant Human DNAM-1/CD226 Fc Chimera (20 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human DNAM-1/CD226 Monoclonal Antibody (Catalog # MAB666). The ND50 is typically 0.1-0.6 µg/mL.

DNAX accessory molecule-1 (DNAM-1), also known as CD226, is a 65 kDa type I transmembrane glycoprotein in the immunoglobulin superfamily (1). Mature human DNAM-1 contains a 236 amino acid (aa) extracellular domain (ECD) with two Ig-like C2-set domains and a 61 aa cytoplasmic region that contains motifs for binding PDZ domains and band 4.1 family proteins (1, 2). Within the ECD, human DNAM-1 shares 50% and 52% aa sequence identity with mouse and rat DNAM-1, respectively. DNAM-1 is expressed on multiple lymphoid and myeloid cell types and interacts with CD155/PVR and Nectin-2/CD112 (3, 4). Ligation of DNAM-1 promotes the activation of NK cells, CD8+ T cells, and mast cells (2‑6), dendritic cell maturation, megakaryocyte and activated platelet adhesion to vascular endothelial cells, and monocyte extravasation; it inhibits the formation of osteoclasts (7‑10). Platelet-endothelium interactions mediated by DNAM-1 enable the metastasis of tumor cells to the lung (11). In activated, but not in resting NK, T, and mast cells, the cis association of DNAM-1 with CD18 contributes to the tyrosine and serine phosphorylation of DNAM-1 during activation (6, 9, 12‑14).
