Cloning

Cloning involves the insertion of a donor DNA fragment into a suitable vector via a process known as ligation. Ligation is performed by DNA ligase, which forms covalent phosphodiester bonds between the 3′-hydroxyl and 5′-phosphate groups of terminal nucleotides of the donor insert and vector DNA. Cloned DNA fragments are typically used for sequence characterization or functional characterization of genes, techniques that require high-quality DNA inserts with no spurious mutations.

In the modern age of molecular biology, PCR isolation of target gene products has become standard and requires polymerase enzymes that yield high-quality products for downstream analysis. Kapa Biosystems has evolved a proofreading polymerase that exhibits exceptional fidelity (100X lower error rate than Taq polymerase), sensitivity and robustness, making it ideally suited for cloning applications sensitive to spurious mutations.
