Fast MultiSite Mutagenesis System is used for generating mutated PCR fragments by introducing mutation sites on overlapping regions. High fidelity TransStart® FastPfu PCR SuperMix is included for amplification. This kit uses proprietary assembly mix and homologous recombination to seamlessly assemble up to six mutagenesis fragments.

• Fast: Amplified with fast & high-fidelity 2×TransStart® FastPfu PCR SuperMix; only 15 minutes for recombination.

• Flexible: Able to be cloned into any site to realize single-site/ multi-site, continuous/non-continuous mutagenesis.

• Efficient: >90% mutagenesis efficiency.


Primer Design

• Both primers contain overlapping region at the 5’ ends and extension region at the 3’ ends, with mutation site on overlapping region, as shown in figure 1.

• Primer length: Both primers (forward and reverse) should be approximately at 25-40 nucleotides in length, excluding the mutation site. Primers should have an overlapping region of 15-25 nucleotides and have an extension region of at least 10 nucleotides.


Electrophoresis Analysis

Amplified PCR products can be checked by electrophoresis with 10 μl of the product on a 1% agarose gel.

• Digestion of PCR Product with DMT
Add 1 μl of DMT enzyme into PCR product, mix thoroughly and incubate at 37oC for 1 hour.

• Purification of PCR products
For PCR product with a single expected band, it is suggested to use PCR Purification Kit to purify PCR products; for PCR product with multibands, we suggest using Quick Gel Extraction Kit to purify PCR products.



•Add 2 μl of assembly products into 50 μl of DMT Chemically Competent Cell (DNA should be added immediately after thawing the cells on ice) and mix by tapping gently. Incubate on ice for 20-30 minutes.

•Heat-shock at 42oC for exactly 45 seconds, quickly remove from 42oC water bath and place on ice for 2 minutes.

•Add 250 μl of SOC or LB medium (pre-warm to room temperature), and incubate at 37oC for 1 hour with shaking at 200 rpm.

•Pre-warm a selective plate at 37oC for 30 minutes.

•Spread 100-200 μl of transformants on the plate and incubate at 37oC overnight


Positive Clone Analysis

Analyze the clones by sequencing.



We suggest performing 25 cycles for PCR. For low yield PCR products, we suggest using up to 30 cycles.
