Aqueous buffered solution containing ≤0.09% sodium azide.


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.


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 CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.


  1. Researchers should determine the optimal concentration of this reagent for their individual applications.
  2. 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.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  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.

The P-3E10 monoclonal antibody specifically recognizes CD298, the β3 subunit of the Na+/K+ ATPase (Sodium/potassium-transporting ATPase subunit beta-3). CD298 is a ~45-55 kDa single-pass, type II membrane protein that is encoded by ATP1B3 (ATPase Na+/K+ transporting subunit beta 3) which belongs to the P-type ATPases superfamily. CD298 is widely expressed on lymphocytes, monocytes, granulocytes, platelets, and on other hematopoietic and nonhematopoietic cells and cell lines. The Na+/K+ ATPase is an integral membrane protein complex with enzymatic activity that mediates the active transport and exchange of sodium and potassium ions across the plasma membrane. This complex is composed of α and β subunits. The α subunit is a 10-membrane-spanning, catalytic protein that contains binding sites for Na +, K + and ATP. The α subunits are associated with the smaller, regulatory glycoprotein β subunits. Upon ATP hydrolysis, the Na+/K+ ATPase transports Na+ ions out of the cell in exchange for K+ ions that are transported in. This establishes a transmembrane electrochemical gradient that is essential for osmoregulation and for the transport of various nutrients and other molecules by cells. The P-3E10 antibody can reportedly inhibit the activation and proliferation of T cells and B cells.

The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.

The BD Horizon™ Red 718 (R718) Dye is part of the BD red family of dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 695-nm and an emission maximum (Em Max) at 718-nm. Driven by BD innovation, R718 is designed to be excited by the red laser (627–640-nm) and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). R718 is a brighter alternative to Alexa Fluor™ 700. R718 is also a bright small molecule alternative to APC-R700 with lower spread into the APC detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
