一般描述
No detectable growth in tryptone soy broth at 30-35 °C for 14 days
生化/生理作用
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.
组分
600-1500 IU beta-lactamase I per vial
60-150 IU beta-lactamase II per vial
60-150 IU beta-lactamase II per vial
单位定义
One unit will hydrolyze 1.0 μmole substrate per min (βI: benzylpenicillin; βII: cephalosporin C) in phosphate buffer, pH 7.0 at 25°C.
外形
Lyophilized powder containing sodium chloride, potassium phosphate, dipotassium phosphate and sorbitol.
