Preparation And Storage
Recommended Assay Procedures
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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- 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).
Companion Products
The Y23-1185 monoclonal antibody specifically recognizes mouse CD39, also known as ectonucleoside triphosphate diphosphohydrolase 1 (NTPDase 1), which is an enzyme on the surface of vascular endothelial cells, antigen presenting cells and activated immune cells. CD39 is encoded by ENTPD1 which belongs to the ectoenzyme family. The catalytic portion of the CD39 is extracellular, where it acts on extracellular nucleoside triphosphates and diphosphates, including ATP and ADP that are hydrolyzed into AMP. Through cell surface CD73 (Ecto-5'-nucleotidase), regulatory T cells can act on extracellular AMP to generate immunosuppressive adenosine. CD39 is involved in the control of the extracellular pool of phosphorylated nucleosides, the suppression of inflammation and immunity, and the regulation of platelet activation.
