The 293C3 monoclonal antibody specifically recognizes CD133 which is also known as Prominin-like protein 1 (PROML1), Prominin-1 (PROM1), hProminin, Hematopoietic stem cell antigen, Macular dystrophy retinal 2 (MCDR2), Stargardt disease 4 autosomal dominant (STGD4), or AC133 antigen. CD133 is an ~120 kDa five-transmembrane, glycoprotein that is encoded by PROM1 (Prominin 1) which belongs to the Prominin gene family. This single-chain, pentaspan transmembrane glycoprotein is comprised of an extracellular N-terminus with two short intracellular sequences and two long extracellular loops followed by an intracellular C-terminus. CD133 is expressed on some cells found in different tissues including the bone marrow, cord and peripheral blood, placenta, liver, pancreas, kidney, lung, retina, brain and heart. It is expressed on a variety of cell types including hematopoietic stem cells and progenitor cells, neural stem cells, developing epithelial cells, precursor endothelial cells, and retinal cells. CD133 is expressed on some cancer cells found in leukemias, melanoma and retinoblastoma. It may serve as a cancer stem cell marker in a number of brain tumors, melanoma, colon cancer, hepatocellular carcinoma, pancreatic adenocarcinoma, and prostate cancer. A mutation in PROM1 has been associated with a form of human retinal degeneration. The 293C3 antibody recognizes a different epitope than the human CD133-specific W6B3C1 antibody.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet for the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. An isotype control should be used at the same concentration as the antibody of interest.
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
