推荐的实验流程
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® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.

- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

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.
