Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

IGF-II Receptor/CI-M6PR Antibody recognizes endogenous levels of total IGF-II receptor (CI-M6PR).


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala1675 of human IGF-II receptor (CI-M6PR). Antibodies are purified by protein A and peptide affinity chromatography.

Insulin-like growth factor II (IGF-II) receptor, also widely known as cation-independent mannose 6-phosphate receptor (CI-M6PR), is a multifunctional type I transmembrane glycoprotein that participates in the internalization of mannose-6-phosphate modified hydrolases and IGF-II from the plasma membrane (1,2). In the absence of ligands, IGF-II receptor is constitutively endocytosed from the cell surface to accumulate in the Golgi apparatus (3). In the presence of ligands, the receptor transports the mannose-6-phosphate modified hydrolases to acidified endosomes and lysosomes (4). The ligand-free receptor is then transported back to the Golgi compartment or the cell surface (4). In several research studies, IGF-II receptor has been recognized as a tumor suppressor in a number of cancers (5-7).
