Preparation And Storage
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
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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 WTH2 monoclonal antibody specifically binds to rat CD1d and crossreacts with mouse CD1d. CD1d is a type I transmembrane glycoprotein that is noncovalently associated with β2-microglobulin. CD1d is expressed on various cell types including subsets of thymocytes, T cells, B cells, monocytes, macrophages, dendritic cells, endothelial cells and epithelial cells. Although structurally similar to MHC Class I antigens, CD1d molecules are rather non-polymorphic and serve to present non-peptide antigens such as endogenous or microbial glycolipids to T lymphocytes (NKT cells). The WTH1 monoclonal antibody reportedly binds to a non-overlapping epitope on rat CD1d and also crossreacts with mouse CD1d when compared with WTH2. Both WTH1 and WTH2 reportedly interfere with antigen recognition by CD1d-restricted T 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.
