The ML5 monoclonal antibody specifically binds to CD24 which is also known as CD24A, signal transducer CD24, small cell lung carcinoma cluster 4 antigen, or BA-1. CD24 is a 35-70 kDa glycophosphatidylinositol (GPI)-linked glycoprotein whose glycosylation pattern is highly variable and cell-type dependent. CD24 is expressed on neutrophils, eosinophils, dendritic cells, neural cells, epithelial cells, muscle cells, and many types of cancer cells. CD24 functions as an adhesion receptor. Several different ligands have been identified for CD24 including CD62P (P-selectin) which is expressed on activated platelets and activated endothelium. CD24 is variably expressed on all B lineage cells, except plasma cells, and can play a role in regulating the activation, proliferation or differentiation of these cells.
This antibody is conjugated to BD Horizon BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes 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).
