Cephalosporin β-Lactamase is a bacterial enzyme that hydrolyzes the β-lactam ring in cephalosporin antibiotics, rendering them inactive. It is primarily used in laboratory and research settings for microbiological assays, such as detecting β-lactamase-mediated antibiotic resistance in bacterial strains. This enzyme is also employed to inactivate β-lactam antibiotics in culture media, facilitating the growth of sensitive microorganisms, and in diagnostic tests to evaluate antibiotic susceptibility. The product is supplied as a sterile, freeze-dried powder with high enzymatic activity (≥2 million units), ensuring stability and solubility for experimental applications.
