Description
The 14D4 monoclonal antibody specifically recognizes the mouse C3a anaphylatoxin chemotactic receptor which is also known as C3aR. C3aR is a 54 kDa glycoprotein that is encoded by C3ar1 (Complement component 3a receptor 1) which belongs to the seven-transmembrane G-protein-coupled receptor (GPCR) superfamily. C3aR is variably expressed on monocytes, macrophages, dendritic cells, neutrophils, basophils, eosinophils, mast cells, T lymphocytes and B lymphocytes. C3aR functions as the cell surface receptor for the C3a anaphylatoxin, the C-terminal cleavage product of C3. C3a acts through C3aR to trigger granulocyte and mast cell degranulation that can further elicit histamine release, enhanced vascular permeability and smooth muscle contraction. C3a has chemotactic properties for eosinophils and mast cells. C3a also causes release of key cytokines from multiple cell types, including IL-1β, IL-6, and TNF.
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 that minimize unconjugated dye and antibody.
1. Researchers should determine the optimal concentration of this reagent for their individual applications.
2. 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.
3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
4. An isotype control should be used at the same concentration as the antibody of interest.
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.
