Description
The L133.1 monoclonal antibody specifically recognizes CD31, the platelet/endothelial cell adhesion molecule-1 (PECAM-1), a 130 to 140-kilodalton (kDa) single-chain integral membrane glycoprotein that is a member of the immunoglobulin gene superfamily. The CD31 antigen is composed of six extracellular immunoglobulin-like domains belonging to the C2 group. C2 domains are also found in other members of the immunoglobulin superfamily, the cell adhesion molecules (CAMs). The CD31 antigen functions as a vascular cell adhesion molecule and is involved in the process of leucocyte migration through the intercellular junctions of vascular endothelial cells. It may also be involved in thrombosis, angiogenesis, wound healing, and inflammation. The CD31 antigen is expressed on endothelial cells, platelets, T-lymphocyte subsets, monocytes, and granulocytes. The CD31 antigen has also been found in metastatic colon carcinoma. The CD31 antigen is the only known member of the CAM family to be expressed on platelets. The antigen is localized at regions of cell-cell contacts and may function as an adhesion molecule, mediating adhesion between leucocytes/endothelial cells, leucocytes/platelets, and endothelial cells/endothelial cells.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).
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 with BD Horizon BUV661 under optimal conditions that minimize unconjugated dye and antibody.
1. This antibody was developed for use in flow cytometry.
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. Researchers should determine the optimal concentration of this reagent for their individual applications.
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.
