3'-O-NH2-2'-dGTP is a 3'-O-amino modified dGTP reversible terminator. The 3'-hydroxyl is capped with a reversible blocking group so that polymerase extension stops after a single incorporation cycle. Key identifiers are CHEMOS CH66028, CAS 1220515-98-9, molecular formula C10H17N6O13P3, and formula-derived molecular weight 522.20.
3'-O-modified nucleotides are used in cyclic reversible-terminator sequencing-by-synthesis workflows: DNA polymerase incorporates the nucleotide, extension pauses after one base, and cap removal regenerates the 3'-OH so synthesis can continue.

Frequently Asked Questions
What is 3'-O-NH2-2'-dGTP?
3'-O-NH2-2'-dGTP is a 3'-O-amino modified dGTP used as a reversible-terminator nucleotide in sequencing-by-synthesis research workflows.
How does a reversible terminator work?
DNA polymerase incorporates the nucleotide, the 3'-O blocking group pauses further extension, and removal of the cap regenerates the 3'-OH so synthesis can continue.
