Opis

General description

Sigma′s DNA Ligation Kit contains all of the reagents necessary to perform DNA ligation reactions. Sticky-end ligations are more efficient than blunt-end ligations; these can be facilitated with the addition of PEG.

Application

Suitable for:

• Joining fragments of DNA into a cloning vector
• Mutagenesis
• Gene anyalysis and structure-function relationships

Biochem/physiol Actions

One of the most important steps in the cloning process is the ligation of linear DNA into a cloning vector. DNA ligations are performed by incubating DNA fragments with appropriately linearized cloning vectors in the presence of buffer, ATP, and DNA ligase. Many parameters affect ligations such as the relative ratio of insert to vector, the quality and type of the DNA ends, the temperature of ligation and the concentration of DNA.

Other Notes
