Alternative Name:CD40 ligand; CD40-L; CD40LG; T-BAM; TNFSF5; TRAP; gp39; hCD40L｜Application:Flow cytometry (Qualified)｜Brand:BD OptiBuild?｜Concentration:0.2 mg/ml｜Immunogen:Human gp39 Protein｜Isotype:Mouse BALB/c IgG1, κ｜Reactivity:Human (Tested in Development)｜Regulatory Status:RUO｜Storage Buffer:Aqueous buffered solution containing ≤0.09% sodium azide.｜描述： The 24-31 monoclonal antibody specifically binds to CD40 Ligand (CD40L) which is also known as CD154, gp39, T-B cell-activating molecule (T-BAM), Tumor necrosis factor ligand superfamily member 5 (TNFSF5), and TNF-related activation protein (TRAP). CD40L (CD154) is an ~39 kDa type II membrane glycoprotein that is encoded by CD40LG. It is expressed on a variety of cell types including activated CD4+ T cells and some CD8+ T cells, NK cells, mast cells and basophils. CD40L (CD154) serves as a ligand for CD40 that is expressed on B cells, macrophages, and dendritic cells.??The expression of CD40L (CD154) by activated T-helper cells costimulates B-cell activation and proliferation through binding to CD40 expressed on B cells. In response to T-dependent antigens, the CD40L (CD154) and CD40 interaction is required for B-lymphocyte differentiation, including immunoglobulin production and isotype switching and memory B cell generation. The 24-31 antibody can reportedly block T cell-B cell interaction and inhibit the subsequent proliferation, differentiation, and memory formation of B cells. It has been reported that patients with X-linked hyper-IgM syndrome have defective expression of functional CD40L (CD154) due to mutations in the CD40LG gene. ｜商品通知：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.Researchers should determine the optimal concentration of this reagent for their individual applications.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.For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page BD Horizon Brilliant Stain Buffer is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,575,303; 8,354,239.BD Horizon Brilliant Ultraviolet 496 is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,227,187; 8,575,303; 8,354,239.｜推薦的實(shí)驗(yàn)流程： 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. For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment.??Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.??The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.??More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385). Note:??When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed.??For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).
