TriLink® 7-Deaza-2'-deoxyguanosine-5'-Triphosphate

Supplier: TriLink BioTechnologies
Description: This deoxyguanosine analog lacks the N7 nitrogen found in the natural guanine nucleobase. Replacement of this nitrogen atom with a carbon atom results in diminished structure of the major groove in DNA and may disrupt base stacking, but does not interfere with Watson-Crick base pairing. This is desirable for applications such as amplification and sequencing of GC-rich nucleic acid sequences.
