Multicolor flow cytometric analysis of CD24 expression on human peripheral blood lymphocytes. Whole blood was stained with Alexa Fluor® 488 Mouse Anti-Human CD19 antibody (Cat. No. 557697) and either BD Horizon™ BV605 Mouse IgG2a, κ Isotype Control (Cat. No. 562778; Left Panel) or BD Horizon™ BV605 Mouse Anti-Human CD24 antibody (Cat. No. 562788; Right Panel). The erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Two-color flow cytometric dot plots show the correlated expression of CD24 (or Ig Isotype control staining) versus CD19 expression for gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from BD Horizon™ BV421 may be observed. Therefore, we recommend that individual compensation controls be performed for every BD Horizon™ BV605 conjugate.

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).
