Specificity

Recognition sequence: 5′-AT/CGAT-3′
Cutting results: a 2-10-fold Cla I overdigestion of 1 μg λ DNA substrate results in 100% cutting
Heat inactivation: Enzyme is not inactivated at 65 °C for 20 minutes.

Application

ClaI is a restriction enzyme that cleaves the DNA recognition sequence 5′-AT/CGAT-3′, generating DNA fragments with 5′-cohesive ends.

Other Notes

Supplied with 10x Restriction Enzyme Buffer SH (B3657).
Comment: Cla I will only partially cleave DNA isolated from E. coli strains that have the dam methylase (dam+ strains).

From Caryophanon latum L site specific restriction endonuclease (ClaI) has been purified, which recognises tha DNA hexanucleotide palindrome 5'-A-T-C-G-A-T-3'. Staggered cleavage generates DNA restriction fragments with 5'-terminal pCG extensions. A CLaI map of bacteriophage lambda has been determined, which indicates
