    Protocol

    Specificity / Sensitivity

    CD133 (D4W4N) XP® Rabbit mAb recognizes endogenous levels of total CD133 protein. The antibody is not sensitive to the glycosylation status of CD133.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein corresponding to the first extracellular domain of human CD133 protein. The epitope has been mapped to a region spanning amino acid residues 257-281, which includes a single N-linked glycosylation site (Asn274).

    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).
