Description
The 11A8 monoclonal antibody specifically recognizes DNAX accessory molecule-1 (DNAM-1) which is also known as CD226, Platelet and T cell activation antigen 1 (PTA1), or T lineage-specific activation antigen 1 antigen (TLiSA1). CD226 is an ~65 kDa type I transmembrane glycoprotein that is encoded by CD226 (CD226 antigen) which belongs to the immunoglobulin superfamily (IgSF). The N-terminal extracellular region of CD226 (DNAM-1) contains two C2 type Ig-like domains which are followed by a transmembrane region and a cytoplasmic tail with predicted phosphorylation sites involved in signaling. This adhesion molecule is expressed on subsets of thymocytes, peripheral CD4+ and CD8+ T cells and B cells, NK cells, monocytes, macrophages, and platelets. CD226 (DNAM-1) associates with leukocyte function associated antigen-1 (LFA-1) and is involved in TCR-mediated signal transduction for T cell proliferation and differentiation. Interactions between the CD226 (DNAM-1) activating receptor and its ligands, CD112 and CD155, results in cellular signaling that promotes innate and adaptive immune responses, including the activation, differentiation, and survival of cytotoxic cells.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.

4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

9. An isotype control should be used at the same concentration as the antibody of interest.

11. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.
