Specificity
Recognition sequence: 5′-GmA/TC-3′
Ligation and recutting results: After 2-10-fold Dpn I overdigestion of 1 μg pBR322 DNA substrate, results in 100% cutting, >30% of fragments can be ligated, and >90% recut.
Heat inactivation: 75 °C for 15 minutes.

Application
DpnI is a restriction endonuclease that is used in molecular biological applications to cleave the recognition sequence 5′-GmA/TC-3′, generating DNA framents with blunt ends.
Other Notes
Supplied with 10x Restriction Enzyme Buffer SA (B7531).
Comment: Since Dpn I will completely cleave only fully methylated pBR322 DNA, cleavage of 95% or more is considered complete digestion.

A deoxyribonuclease specific for methylated DNA was isolated from Diplococcus pneumoniae. The enzyme, an endonuclease, degrades DNA for Escherichia coli to fragments of average molecular weight about half a million; it forms discrete fragments from phage lambda DNA. Methyl-deficient E.

Glucocorticoids are known regulators of the cell cycle, normally exerting an anti-proliferative effect. We have previously shown that glucocorticoids stimulate expression of p57(Kip2), a member of the Cip/Kip family of cyclin-dependent kinase inhibitors which, in some cell types, may account

The human and rat forms of the Kv2.1 channel have identical amino acids over the membrane-spanning regions and differ only in the N- and C-terminal intracellular regions. Rat Kv2.1 activates much faster than human Kv2.1. Here we have studied the

The properties and sources of all known class-I, class-II and class-III restriction endonucleases (ENases) and DNA modification methyltransferases (MTases) are listed and newly subclassified according to their sequence specificity. In addition, the enzymes are distinguished in a novel manner according
