CD33 (PWS44) Mouse Monoclonal Antibody
Specialties: Hematopathology
CD33, also known as gp67 or SIGLEC-3, is a 67 kDa glycosylated transmembrane protein that is a member of the sialic acid-binding immunoglobulin-like lectin (siglec) family.1-3 Although the precise physiological function of CD33 is unknown, it may mediate cell to cell adhesion and modulate inflammatory and immune response.1-3 In normal tissue, anti-CD33 labels myeloid cells (especially myeloid precursors), liver Kupffer cells, lung alveolar macrophages, and placental syncytiotrophoblasts.2,3 In neoplastic tissue, anti-CD33 is useful for the identification of acute myeloid leukemia.2,3
