title: The localization of antibiotics by continuous sucrose gradient density.
abstract: Rat kidney was homogenized and centrifuged by continuous sucrose gradient density. Aminoglycosides and beta-lactam antibiotics were localized in the lysosomes, whereas the localization of tetracyclines was in the mitochondria. This study demonstrated a technique for the localization of antibiotics in the subcellular fractions without the use of a radioactive tracer.
