Application

SpeI is a restriction endonuclease used for molecular biology applications to cut DNA at the recognition site 5′-A/CTAGT-3′, generating DNA fragments with 5′-cohesive ends.

Biochem/physiol Actions

Recognition sequence: 5′-A/CTAGT-3′
Cutting results: a 2-10-fold Spe I overdigestion of 1 μg λ DNA substrate results in 100% cutting.
Heat inactivation: Inactivated at 65 °C for 20 minutes.

Physical form

Solution in 20 mM Tris-HCl, pH 8.0 , 0.1 mM EDTA, 100 mM NaCl, 10 mM 2-mercaptoethanol, 50% glycerol (v/v), 0.2% Triton X-100 (v/v), at 4 °C

Other Notes

Supplied with 10x Restriction Enzyme Buffer SH (B3657).

Successful carbapenem-based chemotherapy for the treatment of Pseudomonas infections has been seriously hindered by the recent appearance of IMP- and VIM-type metallo-beta-lactamases, which confer high-level resistance to carbapenems and most other beta-lactams. Recently, multidrug-resistant Pseudomonas putida isolates for which carbapenem
