Preparation And Storage

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.

Recommended Assay Procedures

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.

Product Notices

  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 J90-462 monoclonal antibody specifically recognizes CD6. CD6 is a 105-130 kDa type I transmembrane glycoprotein that belongs to the scavenger receptor family. It is expressed on most thymocytes and peripheral T cells. CD6 is highly expressed on CD3-high thymocytes and expressed at lower levels on CD4+ CD8+ double positive and CD4+CD8- or CD4-CD8+ single positive thymocytes. CD6 is also reportedly expressed at low levels by some neurons.  CD6 serves as a receptor for CD166, also known as Activated Leukocyte Cell Adhesion Molecule (ALCAM). CD6 plays a role in adhesion and migration during organogenesis. The CD6 intracellular domain is constitutively phosphorylated which suggests that CD6 may play a signaling role in T cell activation.

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.
