Detection of Human CD24 by Western Blot. Western blot shows lysates of Daudi human Burkitt's lymphoma cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human CD24 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5247) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for CD24 at approximately 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

CD24 (signal transducer 24; also HSA/heat shock antigen) is a variably glycosylated, 35‑50 kDa member of the CD24 family of proteins. It is a GPI‑linked sialoprotein that is expressed on B cell precursors and unactivated B cells, keratinocytes, and neutrophils and thymocytes. Ligation of CD24 appears to inhibit B cell differentiation, likely through the initiation of apoptosis. Potential CD24 ligands include P‑Selectin. The human CD24 precursor is 80 amino acids (aa) in length. It contains a 26 aa signal sequence plus a cleavable C‑terminal propeptide (aa 60‑80). There is one potential alternate start site at Met5. Over aa 27‑59, human CD24 shares only 30% aa identity with mouse CD24.
