Application

The reagent is designed for Flow Cytometry analysis of human blood cells using 4 µL reagent / 100 µL of whole blood or 10⁶ cells in a suspension. The content of a vial is sufficient for 100 tests.

Biochem/physiol Actions

Association of CD33 (cluster of differentiation 33) with sialic acid-containing ligands causes suppression of proinflammatory pathways in monocytes and macrophages. It is mainly involved in anti-inflammatory signaling, cell adhesion and endocytosis functions. CD33 also works as a myeloid differentiation marker. Mutations in the CD33 gene are associated with Alzheimer’;s disease susceptibility and acute myeloid leukemia treatment efficacy. In microglia, increase in the expression of CD33 decreases amyloid β peptide phagocytosis.

General description

Myeloid cell surface antigen CD33, (cluster of differentiation 33) also known as SIGLEC3, siglecs (sialic acid binding Ig-like lectins) and GP67, belongs to the CD33-related SIGLEC gene family. It is a type 1 transmembrane protein and contains two immunoglobulin-like extracellular domains, a single transmembrane area and two intracellular inhibitory motifs. The CD33 gene is mapped to human chromosome 19q13.41.

The antibody WM53 reacts with CD33, a 67 kDa type I transmembrane glycoprotein (immunoglobulin superfamily) expressed on myeloid progenitors, monocytes, granulocytes, dendritic cells and mast cells; it is absent on platelets, lymphocytes, erythrocytes and hematopoietic stem cells.
