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.
Physical form
Lyophilized powder containing sodium chloride, potassium phosphate, dipotassium phosphate and sorbitol.
Other Notes
600-1500 IU beta-lactamase I per vial
60-150 IU beta-lactamase II per vial
60-150 IU beta-lactamase II per vial
One unit will hydrolyze 1.0 μmole substrate per min (βI: benzylpenicillin; βII: cephalosporin C) in phosphate buffer, pH 7.0 at 25°C.

The misuse of antibiotics in health care has led to increasing levels of drug resistant infections (DRI's) occurring in the general population. Most technologies developed for the detection of DRI's typically focus on phenotyping or genotyping bacterial resistance rather than

Signal transducer and activator of transcription 5 (Stat5) is essential for cytokine-regulated processes such as proliferation, differentiation, and survival in hematopoietic cells. To investigate the role of Stat5 in osteoclasts, we generated mice with an osteoclast-specific conditional deletion of Stat5
