    Fidelity at its finest

    Q5 High-Fidelity DNA Polymerase sets a new standard for both fidelity and performance.

    Five quality features of Q5:
    • Fidelity - the highest fidelity amplification available (>50X higher than Taq)
    • Robustness - high specificity and yield with minimal optimization
    • Coverage - superior performance for a broad range of amplicons (from high AT to high GC)
    • Speed - short extension times
    • Amplicon length - robust amplifications up to 20 kb for simple templates, and 10 kb for complex

    Competent Cells

    For cloning experiments choose from several high efficiency competent cell strains. These E. coli strains are T1 phage resistant and are endA deficient for high quality plasmid preparations. NEB 5-alpha strains are enhanced DH5α™ derivatives, while NEB 10-beta is a DH10B™ derivative. NEB also offers a unique fast growing strain (NEB Turbo) and a dam/dcm strain.

    NEB offers several strains with varying levels of expression control, each with phage T1 resistance and extremely high transformation efficiencies:

    SHuffle strains enable disulfide bond formation in the cytoplasm.

    BL21 (DE3) is available for routine T7 expression in addition to Lemo21(DE3) for tunable expression of difficult targets such as membrane proteins, toxic proteins and proteins prone to insoluble expression.

    • Free of animal products
    • T1 phage resistance (fhuA2) Media and control plasmid included with most strains
    • A variety of convenient formats, including single use transformation tubes and, on request, 96 well plates
    • Bulk sales capabilities with custom packaging.
    • No additional dry ice charge
