  • OneTaq® Quick-Load® 2X Master Mix with Standard Buffer

    Description

    OneTaq® Quick-Load® 2X Master Mix with Standard Buffer is an optimized, ready-to-use blend of Taq and Deep VentR ™ DNA Polymerases ideally suited to routine PCR applications from a variety of templates, including pure DNA solutions, bacterial colonies and cDNA products. The 3´→5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase (1). The convenient quick-load master mix formulation contains dNTPs, MgCl2, buffer components and stabilizers as well as two commonly used tracking dyes for DNA gels. On a 1% agarose gel in 1X TBE, Xylene Cyanol FF migrates at ~4 kb and Tartrazine migrates at ~10 bp. Both dyes are present in concentrations that do not mask comigrating DNA bands.

    Amplification of a selection of sequences with varying GC content from human and C. elegans genomic DNA using OneTaq DNA Polymerase. Amplicon sizes are indicated next to gel, and GC content is indicated above gel. Marker M is the 1 kb DNA Ladder (NEB #N3232 ).

    Product Source

    An E. coli strain that carries the Taq DNA Polymerase gene from Thermus aquaticus YT-1 and an E. coli strain that carries the Deep VentR DNA Polymerase gene from Pyrococcus species GB-D.

    Quality Control

    Quality Control Assays

    The following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
    • PCR Amplification (DNA Polymerase):

      The polymerase master mix is tested in a polymerase chain reaction (PCR) using a control template and specific primers, resulting in the expected product.

    Notes

    1. Product specifications for individual components in the OneTaq Quick-Load 2X Master Mix with Standard Buffer are available separately.
    2. OneTaq Quick-Load 2X Master Mix with Standard Buffer is stable for fifteen freeze-thaw cycles when stored at -20°C.
    3. OneTaq Quick-Load 2X Master Mix with Standard Buffer is also stable for one month at 4°C, so for frequent use, an aliquot may be kept at 4°C.
