Novobiocin Sodium Salt is an antibiotic used to inhibit bacterial growth, especially for the isolation of Gram-positive bacteria. This 100g powder formulation is a valuable tool for laboratory research, where it is primarily used to study bacterial resistance mechanisms and to control bacterial contamination in culture media. Novobiocin inhibits DNA gyrase, an essential enzyme in bacterial replication, making it effective for selective bacterial inhibition. Laboratories use this antibiotic for a variety of microbial assays, including testing bacterial susceptibility and studying the biochemical properties of different bacterial strains.
