7-Deaza-2'-dGTP material number and pack size:
Material Number Pack Size
10987891103 100 mL 1,000 µmol
Will be supplied as ''7-Deaza-2'-deoxy-GTP, Di-Li''. Unit of measure is ''μmol''.
Use 7-Deaza-dGTP instead of dGTP in primer-extension reactions or PCR and receive a better resolution of GC-rich regions.
Use 7-Deaza-dGTP as a substrate for most DNA polymerases, including Taq DNA polymerase.
7-Deaza-dGTP is used in the dideoxy-chain termination sequencing methods, in place of dGTP to overcome compression problems in gel electrophoresis when sequencing GC-rich stretches of DNA.
