A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 20X Phosphate Buffered Saline (PBS): (#9808) To prepare 1 L 1X PBS: add 50 ml 20X PBS to 950 ml dH2O, mix.
  2. Incubation Buffer: Dissolve 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.

B. Immunostaining

  1. Count cells using a hemacytometer or alternative method.
  2. Aliquot 0.5-1x106 cells into each assay tube (by volume).
  3. Add 2-3 ml Incubation Buffer to each tube and rinse by centrifugation. Repeat.
  4. Resuspend cells in 100 µl of diluted primary antibody (prepared in incubation buffer at the recommended dilution).
  5. Incubate for 1 hr at room temperature.
  6. Wash by centrifugation in 2-3 ml incubation buffer.
  7. Resuspend cells in the appropriate volume of PBS and analyze on flow cytometer.

CD24 (M1/69) Rat mAb (violetFluor™ 450 Conjugate) recognizes endogenous levels of total CD24 protein. This antibody detects an epitope within the extracellular domain.

Species Reactivity:


This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography. The purified antibody was conjugated under optimal conditions, with unreacted dye removed from the preparation.

This Cell Signaling Technology antibody is conjugated to violetFluor™ 450 and tested in-house for direct flow cytometric analysis in mouse cells.

CD24, also know as heat stable antigen HSA, is a P-selectin ligand involved in adhesion. It is a GPI-anchored glycoprotein expressed on many types of cells, including hematopoietic cells, neural cells, and epithelial cells. CD24 is widely used to delineate stages of lymphocyte development (1-3). It also binds to Siglec-10 in humans or Siglec-G in mice (4,5). CD24 is frequently used as a marker to identify and isolate cancer stem cells in various cancer types (6,7).
