CST, 69914SF, CD133 (D4W4N) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying CD133. Validated for Western Blotting,IHC Leica Bond,Immunohistochemistry (Paraffin). Highly specific and rigorously validated in-house, CD133 (D4W4N) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #69914) is ready to ship. Product Usage Information This product is the carrier free version of product #86781. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 86781 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity CD133 (D4W4N) Rabbit Monoclonal Antibody (BSA and Azide Free) 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).
