Specificity/Sensitivity

CD33 (F3S8B) Rabbit Monoclonal Antibody recognizes endogenous levels of total CD33 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of mouse CD33 protein.

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).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
