General description

dGTP is a 100 mM clear, colorless solution of the lithium salt (pH 7).
dGTP solution in water (pH 7), 100 mM, lithium salt.


2′-Deoxyguanosine 5′-triphosphate trisodium salt is utilized for methods such as DNA sequencing, PCR and other DNA polymerase based DNA synthesis and repair techniques.

Use dGTP, lithium salt, for DNA sequencing, labeling, and all types of amplification reactions or primer-extension reactions.

Biochem/physiol Actions

2′-Deoxyguanosine 5′-triphosphate is used in vivo synthesis for the synthesis of DNA via DNA polymerases.


Typical analysis:
• ≥98% dGTP (HPLC), ≤1.5% dGDP (HPLC), ≤0.5% dGMP (HPLC)
• Absorbance determination A250/A260, A280/A260, A290/A260
• DNase activity negative, according to the current Quality Control procedures
• Suitability for PCR

Unit Definition

1 μmol dGTP = 13.7 A252 units

Other Notes

For life science research only. Not for use in diagnostic procedures.

Our PCR Grade deoxynucleotides are even purer than the lithium salts, to ensure excellent performance in your PCRs. PCR Grade deoxynucleotides contain the sodium salt of the nucleotide in PCR Grade Water.
For your convenience, some of our deoxynucleotides are also available in:
• nucleotide sets (all 4 nucleotides in separate vials)
• ready-to-use nucleotide mixes (premixed solutions of all 4 nucleotides)

They are also vital components of:
• kits (dNTPs, buffer, and polymerase in separate vials)
• ready-to-use mixes [polymerase, nucleotides, and buffer (premixed 2x solutions)]
