2'-Deoxyguanosine 5'-diphosphate sodium salt (dGDP sodium salt) is used in molecular biology and biochemistry research as an intermediate in nucleotide metabolism. It serves as a substrate for enzymes such as nucleoside diphosphate kinase, which phosphorylates it to form dGTP, a key building block for DNA synthesis. Employed in enzymatic assays to investigate nucleotide interconversions, enzyme kinetics, and salvage pathways. Plays a role in studies of DNA replication, repair mechanisms, and mutagenesis by providing insights into deoxyribonucleotide pool regulation. Additionally, utilized in research on genetic disorders, cancer, and the development of antiviral agents and diagnostic tools targeting nucleotide-related pathways.
