Detection of CD24 in Human Blood Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were stained with Mouse Anti-Human CD19 PE‑conjugated Monoclonal Antibody (Catalog # FAB4867P) and either (A) Mouse Anti-Human CD24 APC‑conjugated Monoclonal Antibody (Catalog # FAB5247A) or (B) Mouse IgG2A Allophycocyanin Isotype Control (Catalog # IC003A).

CD24, also known as heat stable antigen (HSA), is a heavily and variably glycosylated 35‑60 kDa GPI-linked sialoprotein that is expressed on B cells, T cells, keratinocytes, and myofiber synaptic nuclei and is up‑regulated in a wide variety of cancers. It is also a marker for exosomes released into the urine and amniotic fluid. CD24 binds to P-Selectin on activated platelets and vascular endothelial cells. CD24 ligation induces tumor cell apoptosis and is important for the deletion of autoreactive T cells. Mature human CD24 shares 30% and 42% aa sequence identity with mouse and rat CD24, respectively.
