Description
The 20/70 monoclonal antibody specifically binds to CD88, which is also known as, Complement component 5a receptor 1 (C5ar1), C5a anaphylatoxin chemotactic receptor, or C5a receptor (C5aR). CD88 belongs to the rhodopsin family of seven-transmembrane G protein-coupled receptors and mediates its effects by binding to the complement activation product, C5a. CD88 is expressed on leucocytes including, neutrophils, monocytes, macrophages, and eosinophils. CD88 may also be expressed on alveolar epithelial cells, endothelial cells, neural stem cells, oligodendrocytes, and on parenchymal cells of lung, liver, kidney and heart. Binding of the proinflammatory C5a anaphylatoxin to CD88 results in G-protein coupling and intracellular signal transduction that mediates intracellular calcium release, chemotaxis, degranulation, cytokine production, and superoxide anion production. The 20/70 antibody can block binding of C5a to CD88 and thus inhibit its biological functions.
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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
5. An isotype control should be used at the same concentration as the antibody of interest.
6. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
7. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
8. 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.
9. Researchers should determine the optimal concentration of this reagent for their individual applications.
