Protocol
Specificity / Sensitivity
CD33 Antibody recognizes endogenous levels of total CD33 protein.
Species Reactivity:
Human
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human CD33 protein. Antibodies are purified by peptide affinity chromatography.
Background
CD33, a type I transmembrane protein, is a sialic acid-binding Ig-like lectin 3 (Siglec-3) of the Ig superfamily, and human CD33 binds preferentially to alpha-2, 6-linked sialic acid. Upon binding to its ligands, CD33 transduces inhibitory signaling through the immunoreceptor tyrosine-based inhibitory motif (ITIM) in its intracellular domain, inhibiting cellular functions such as phagocytosis. In addition, CD33 is also involved in other processes, such as adhesion (1-3). Due to its exclusive expression on hematopoietic cells, particularly the myeloid lineage and their progenitors, CD33 has been actively pursued as a therapeutic target against acute myeloid leukemia (AML) (4,5). CD33 may also be involved in Alzheimer’s Disease (AD) (6-8).
