Description
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.
Bead-based compensation or unmixing controls, such as BD® CompBeads or BD™ SpectraComp™, can be used as surrogates to assess fluorescence spillover when bound to fluorochrome-conjugated antibodies. Although these beads have spectral properties similar to cells, variations in spectral emission may occur, resulting in differing spillover values compared to biological controls. Therefore, it is considered best practice to compare the spillover obtained from cells and bead-based controls when using BD® CompBeads or BD™ SpectraComp™ for the first time, to ensure they are appropriate for the intended application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
3. 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.
4. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
6. An isotype control should be used at the same concentration as the antibody of interest.
