ddATP

SKU: orb65197

Description

ddATP (2',3'-Dideoxyadenosine-5'-triphosphate, Lithium salt) is a high-purity chain-terminating nucleotide analog widely used in DNA sequencing, primer extension, and molecular biology research. As a modified form of dATP, ddATP is enzymatically incorporated into DNA strands but lacks the essential 3'-OH group, resulting in immediate termination of DNA synthesis. This property makes it an essential reagent for Sanger sequencing and controlled DNA polymerization studies.
