Description
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.
Put all BD® AbSeq Reagents to be pooled into a Latch Rack for 500 µL Tubes (Thermo Fisher Scientific Cat. No. 4900). Arrange the tubes so that they can be easily uncapped and re-capped with an 8-Channel Screw Cap Tube Capper (Thermo Fisher Scientific Cat. No. 4105MAT) and the reagents aliquoted with a multi-channel pipette. BD® AbSeq tubes should be centrifuged for ≥ 30 seconds at 400 × g to ensure removal of any content in the cap/tube threads prior to the first opening.
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 and conjugated to BD® AbSeq oligonucleotide under optimal conditions.
1. This reagent has been pre-diluted for use at the recommended volume per test. Typical use is 2 µl for 1 × 10^6 cells in a 200-µl staining reaction.
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. 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.
4. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
