dNTP (2'-deoxynucleoside 5'-triphosphates) solutions set, containing dATP, dCTP, dGTP, dTTP are supplied as 10 mM aqueous solution at pH 7.0. dNTPs are available individually, as a convenient set of 10 mM solutions of each dATP, dTTP, dCTP and dGTP for direct use in PCR, reverse transcription, labeling and other applications. Greater than 99% purity confirmed by HPLC Free of Human and E.coli DNA Highly stable: stable after multiple freeze-thaw cycles 85-90% of dNTPs remain in triphosphate form after 30 cycles of PCR (1 min at 94oC; 3 min at 72o C).
