Gentamicin

Gentamicin (CAS No.: 1403-66-3) is a broad spectrum aminoglycoside antibiotic complex of microbial origin, historically obtained from Micromonospora species, and is primarily categorized as an antibacterial research reagent used in microbiology, cell biology, and preclinical pharmacology workflows; in biomedical research it functions by binding the bacterial ribosomal small subunit to disrupt translational fidelity and protein synthesis, thereby suppressing the growth of both Gram positive and Gram negative bacteria, while also being widely used to control bacterial contamination and inhibit multiple mycoplasma strains in tissue culture systems, and additional biochemical evidence indicates inhibition of DNase I activity at low millimolar levels, supporting utility in studies of nuclease associated processes under defined assay conditions; reported antibacterial potency for aminoglycosides is typically discussed in the micromolar to low millimolar concentration context depending on organism and assay format, whereas cell culture supplementation and in vivo experimental exposure ranges vary across protocols and should be optimized according to model specific tolerability and study endpoints; common research applications include selective pressure and contamination control in in vitro cell models, mechanistic investigations of bacterial stress responses and ribosomal decoding, infection related pharmacology studies including ocular infection research paradigms, and induction of renal injury phenotypes in animal models for pathophysiology and drug safety investigations, with the concentrations or doses used in experiments typically depending on specific experimental designs and research objectives.
