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

- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.

The L363 monoclonal antibody specifically recognizes the complex formed by alpha-Galactosylceramide (α-Galactosylceramide) and Mouse CD1d, Mouse α-GalCer:CD1d Complex. The α-Galactosylceramide (α-GalCer) glycolipid can activate mouse and human iNKT cells. α-GalCer has been used as a model antigen for the analyses of iNKT cell-mediated immunity. This glycolipid binds to the nonclassical MHC I CD1d molecule expressed on antigen presenting cells such as dendritic cells. The cell-bound α-GalCer:CD1d Complex can subsequently be recognized by iNKT cells through their invariant Vα14-Jα18 TCR α chain. Activated iNKT cells have a broad array of effector and regulatory immune functions due to their rapid response to antigens by production of Th1 and Th2 cell-associated cytokines and activation of effector functions performed by other leucocytes. The L363 antibody can reportedly block activation of iNKT cells by the Mouse α-GalCer:CD1d Complex.
