Description
The C8.6 monoclonal antibody specifically recognizes human IL-12 p40 that is encoded by IL12B (interleukin 12B). The antibody binds to IL-12 p40 monomers and homodimers as well as to the p40 subunit of the heterodimeric cytokines, IL-12 p70 (p35/p40) and IL-23 (p19/p40). These cytokines are produced by a variety of cells, including activated monocytes, macrophages, neutrophils, and dendritic cells. IL-12 p40 monomers and homodimers can block the binding of heterodimeric IL-12 to its receptor. IL-12 promotes the generation of Th1 cells and activates NK cells, Group 1 innate lymphoid cells (ILC1), and cytotoxic T cells leading to production of IFN-γ, TNF, granzymes, and perforin. IL-23 promotes the generation and activation of Th17 cells and other effector cells, including γδ T cells, NKT cells, MAIT cells, and ILC3 that can produce cytokines including IL-17A, IL-17F, IL-22, GM-CSF, TNF, and IL-6. The immunogen used to generate the C8.6 hybridoma was the purified p40 subunit of human IL-12. The C8.6 antibody is a neutralizing antibody and can reportedly inhibit the biological activities of IL-12 and IL-23.
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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular 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. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
5. 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.
