Nitrocefin is widely used as a chromogenic cephalosporin substrate for the detection of beta-lactamase activity. It is particularly valuable in microbiological assays to identify antibiotic resistance in bacteria. When beta-lactamase enzymes are present, they hydrolyze Nitrocefin, resulting in a visible color change from yellow to red. This property makes it a crucial tool in clinical laboratories for rapid and accurate diagnosis of beta-lactamase-producing organisms. Additionally, Nitrocefin is employed in research settings to study the mechanisms of beta-lactam resistance and to evaluate the efficacy of beta-lactamase inhibitors. Its sensitivity and specificity make it a preferred choice for both diagnostic and investigative applications in microbiology.
