    Polymerases and Amplification Technologies

    New England Biolabs supplies a selection of highly pure nucleotides for use with DNA and RNA polymerases.

    Deoxynucleotide Solution Set (NEB #N0446

    The Deoxynucleotide Solution Set contains four separate 100 mM solutions of ultrapure nucleotides (dATP, dCTP, dGTP, and dTTP).

    Deoxynucleotide Solution Mix (NEB #N0447)

    The Deoxynucleotide Solution Mix is an equimolar mixture of ultrapure dATP, dCTP, dGTP, and dTTP. Each nucleotide is present at a concentration of 10 mM in the mixture for a total dNTP concentration of 40 mM.

    7-deaza-dGTP* (NEB #N0445)

    7-deaza-dGTP is a useful additive for the PCR of GC-rich templates; contains a 5 mM solution of 7-deaza-dGTP as a dilithium salt.

    Acyclonucleotide Set (NEB #N0460)

    The Acyclonucleotide Set contains four separate tubes of acyNTPs (acyATP, acyCTP, acyGTP and acyTTP), supplied as a dry powder.

    dATP Solution (NEB #N0440)

    The dATP solution contains 0.25 ml of 100 mM ultrapure dATP.

    Ribonucleotide Solution Set (NEB #N0450)

    Ribonucleotide Solution Set consists of four separate 100 mM solutions of ATP, GTP, CTP and UTP.

    Ribonucleotide Solution Mix (NEB #N0466)

    The Ribonucleotide Solution Mix is an equimolar mixture of ribonucleotide triphosphates (rATP, rCTP, rGTP and rUTP). Each is supplied at a concentration of 80 mM for a total concentration of 320 mM.

    DNA Polymerase Selection Chart

    NEB offers a guidelines for choosing the correct DNA polymerase for your application by providing a list of specific properites.
    Several factors govern which polymerase should be used in a given application, including: 

    Template/product specificity: Is RNA or DNA involved? Is the 3´ terminus at a gap, nick or at the end of the template? 

    Removal of existing nucleotides: Will the nucleotide(s) be removed from the existing polynucleotide chain as part of the protocol? If so, will they be removed from the 5´ or the 3´ end? 

    Thermal stability: Does the polymerase need to survive incubation at high temperature or is heat inactivation desirable? 

    Fidelity: Will subsequent sequence analysis or expression depend on the fidelity of the synthesized products?
