Description
This HB14 monoclonal antibody specifically recognizes CD40 which is also known as Tumor necrosis factor receptor superfamily member 5 (TNFRSF5). CD40 is an ~45-48 kDa single-pass type I transmembrane glycoprotein. CD40 is expressed on B lymphocytes, monocytes, macrophages, dendritic cells, endothelial cells, fibroblasts, keratinocytes, and CD34+ hematopoietic progenitor cells. CD40 serves as a receptor for CD154 (CD40 Ligand or CD40L). CD40:CD154 interactions costimulate B cell growth, differentiation, and immunoglobulin isotype switching in antibody responses to T-dependent antigens as well as the generation of memory B cells and cytokine production by monocytes and dendritic cells. The HB14 antibody reportedly crossreacts with CD40 expressed by several non-human primates including Rhesus and Cynomolgus Macaques as well as Olive Baboons.
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.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.
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® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
6. 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.
