repliQa HiFi Assembly Mix is intended for molecular biology applications. This product is not intended for the diagnosis, prevention or treatment of a disease.
The repliQa™ HiFi Assembly Mix simplifies the construction of recombinant DNA through seamless assembly of multiple DNA fragments in a single, isothermal reaction. Similar in principle to the Gibson Assembly® Method, the high efficiency repliQa HiFi Assembly Mix is ideal for a range of genetic engineering applications including:
- Routine molecular cloning
- Site-directed mutagenesis
- Synthetic biology
- Construction of libraries for directed evolution studies
The concentrated (10x), two component format allows flexibility in design of assembly reactions and compatibility with less concentrated DNA samples. The repliQa Mix has been optimized for use with a total input quantity of DNA fragments in the range of 0.03 to 0.5 pmols. Assembly of up to five DNA fragments is recommended, though the repliQa Mix has been used successfully for more complex assemblies. The mix supports assembly of multiple DNA fragments in a single 1-hr reaction.
High efficiency cloning from low DNA inputs
repliQa HiFi Assembly Mix increases transformation efficiency without the need for diluting or purifying the assembly reaction prior to transformation of competent cells, resulting in less hands-on- time and faster workflows.
Assemble larger number of fragments
repliQa HiFi Assembly Mix allows for large inserts to be cloned at a very high efficiency resulting in significantly more positive clones eliminating the need to repeat experiments due to erroneous or insufficient clones.
The repliQa™ HiFi Assembly Mix simplifies the construction of recombinant DNA through scarless assembly of multiple DNA fragments in a single, isothermal reaction.
Dilution of the assembly reaction not required – high transformation efficiency, less hands-on time
Three DNA fragments containing 23 bp overlaps were generated by PCR, DpnI treated umn purified.
The three fragments, 4.2 kb, 3.1 kb, and 400 bp in size, were combined in a 1:1.4:5 molar ratio. Total DNA quantities used are indicated (x-axis) and reacted at 50 °C for 60 minutes according to the protocol. One microliter of the undiluted assembled products or one microliter of a 4-fold dilution of the assembled products was used to transform 30 μl of chemically competent cells.
High transformation efficiency greater number of fragments
PCR fragments containing 30 bp overlaps were DpnI treated, purified, and assembled according to the protocol.
PCR fragments containing 30 bp overlaps were DpnI treated, purified, and assembled according to the protocol. Reactions contained the indicated number of DNA fragments (0.1 pmol each) and were incubated at 50 °C for 60 minutes. 1 ul of the reactions were used to transform 30 µl of chemically competent cells.

In contrast to traditional cloning, there is no requirement for restriction endonucleases and unique restriction sites.Is there a preferred method for transforming E.coli with the assembled DNA?The products of the repliQa HiFi Assembly reaction can be introduced into E.coli either by chemical transformation or electroporation. If electroporation is to be used for transforming cells, we recommend first diluting the assembly reaction 1:5 in high purity water.Click here to see all FAQsWhen should the DpnI be used?If plasmid DNA is used as PCR template for generation of fragments for assembly, it is recommended to treat the PCR reactions with DpnI prior to the assembly reaction to eliminate residual methylated plasmid that could give rise to colonies lacking the assembled product of interest.
