Molecular cloning, a key component of the molecular biology workflow, is used to assemble recombinant DNA molecules and to direct their replication. In the molecular cloning workflow, the DNA to be cloned is identified and treated with enzymes to generate DNA fragments. These fragments are then combined with vector DNA to generate recombinant DNA molecules.

PCR cloning kits

An advanced positive-selection system for high-efficiency cloning of PCR products generated with any thermostable DNA polymerase. Ideal for both blunt-end and sticky-end cloning.

A TA system for direct one-step cloning of PCR products with 3’-dA overhangs generated by Taq DNA polymerase and other thermostable DNA polymerases which lack proofreading activity.

Ligation- independent cloning (LIC)

Designed for fast and efficient LIC and tight regulation of gene expression in E. coli. LIC enables high-cloning efficiencies of more than 95% and eliminates the need for restriction enzyme digestion and ligation steps.

DNA ligation and end repair

Allows fast sticky-end or blunt-end DNA ligation, typically in only 5 minutes at room temperature.

Used for blunting and phosphorylation of DNA ends, typically in just 5 minutes, for subsequent use in blunt-end ligation.

Molecular Cloning Enzymes and Reagents

Enzymes for modification of DNA ends, such as T4 DNA ligase, alkaline phosphatase, PNK, Klenow fragment and T4 DNA Polymerase.

IPTG and X-gal for blue/white colony selection.

pUC plasmid and lambda DNA for use as molecular cloning vectors.
