Introduction
CD33
is putative adhesion molecule of myelomonocytic-derived cells which mediates
sialic-acid dependent binding to cells. CD33 prefers to bind to
alpha-2,6-linked sialic acid. The sialic acid recognition site is masked by cis
interactions with sialic acids on the same cell surface. In the immune
response, CD33 perform as an inhibitory receptor upon ligand induced tyrosine
phosphorylation by recruiting cytoplasmic phosphatases through their SH2
domains which block signal transduction through dephosphorylation of signaling
molecules. In addition, CD33 induces apoptosis in acute
myeloid leukemia.
Description
CD33 Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 265 amino acids (18-259 a.a) and
having a molecular mass of 29.1kDa.
CD33 is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered clear solution.
Formulation
CD33 protein solution (1mg/ml) containing 20mM Tris-HCl
buffer (pH 8.0), 0.4M Urea, and 10% glycerol.
