KLD Enzyme Mix is a unique blend of Kinase, Ligase and DpnI enzymes. This formulation allows efficient phosphorylation, intramolecular ligation/circularization and template removal in a single 5 minute reaction step at room temperature. This master mix is a component of the Q5 Site-Directed Mutagenesis Kits and it has been designed for use with fragments that have been PCR-amplified by Q5 Hot Start High-Fidelity DNA Polymerase.

Q5 Site-Directed Mutagenesis Kit Overview
This kit is designed for rapid and efficient incorporation of insertions, deletions and substitutions into double-stranded plasmid DNA. The first step is an exponential amplification using standard primers and a master mix formulation of Q5 Hot Start High-Fidelity DNA Polymerase. The second step involves incubation with a unique enzyme mix containing a kinase, a ligase and DpnI. Together, these enzymes allow for rapid circularization of the PCR product and removal of the template DNA. The last step is a high-efficiency transformation into chemically competent cells (provided).

Properties & Usage



Notes
  • This product has been designed to be used on dsDNA fragments that have been amplified by Q5 High-Fidelity Polymerase specifically.
  • This product is to serve as a companion product for our Q5 Site-Directed Mutagenesis Kits.
  • For best results, primers should be designed and annealing temperatures calculated using NEBaseChanger, the NEB online primer design software.

Tech Tips
  • Only use 5 μl of the KLD reaction in the transformation. If more KLD reaction is added, a buffer exchange step, such as PCR purification, should be included prior to transformation.

  • Only use 1 μl of PCR product in the KLD reaction. Carrying too much PCR product forward can decrease transformation efficiency. If the PCR yield is low, more product can be added to the KLD reaction, however a buffer exchange step, such as PCR purification, must be included prior to transformation.

  • Use NEBaseChanger™ to design primers and calculate annealing temperature
