General description

No detectable growth in tryptone soy broth at 30-35 °C for 14 days

Biochem/physiol Actions

β-Lactamases exhibit high carbapenemase activity. β-lactamases can destroy the β-lactam ring. True carbapenemases has the ability to hydrolyse several β-lactam ring containing carbapenems like meropenem, doripenem, imipenem and ertapenem.

Components

600-1500 IU beta-lactamase I per vial
60-150 IU beta-lactamase II per vial

Unit Definition

One unit will hydrolyze 1.0 μmole substrate per min (βI: benzylpenicillin; βII: cephalosporin C) in phosphate buffer, pH 7.0 at 25°C.

Physical form

Lyophilized powder containing sodium chloride, potassium phosphate, dipotassium phosphate and sorbitol.
