Product Overview
Clone AFDH-18 is a rabbit monoclonal antibody that recognizes ribonucleoside-diphosphate reductase large subunit (gene RRM1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 90.1 kDa, and the supplier reports an observed band at about 90 kDa.
RRM1 is the large catalytic subunit of ribonucleotide reductase, the enzyme that converts ribonucleotides into the deoxyribonucleotides needed for DNA synthesis and repair. It carries the active site and allosteric sites that balance dNTP pools, and it is a direct target of the nucleoside analog gemcitabine.
