Protocol Available protocols: Immunohistochemistry (Paraffin) Specificity / Sensitivity CD133 (D2V8Q) Rabbit Monoclonal Antibody (Alexa Fluor Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the 1st extracellular loop of human CD133 protein. The epitope has been mapped to a region spanning amino acid residues 303-312. Background CD133, also known as Prominin, was first described as a cell surface marker recognized by monoclonal antibody AC133 on putative hematopoietic stem cells (1). Subsequent cDNA cloning indicated that CD133 is a five-transmembrane protein with a predicted molecular weight of 97 kDa. Due to heavy glycosylation, its apparent molecular weight is 130 kDa as determined by SDS-PAGE analysis (2). Besides blood stem cells, CD133 is expressed on and used to isolate other stem cells, including cancer stem cells (3-7). A deletion mutation in CD133 produces aberrant protein localization and may result in retinal degeneration in humans (8).
