Tetracycline (hydrochloride)

Tetracycline is a bacteriostatic agent that acts by preventing aminoacyl tRNA from binding to the ribosome A site, thus inhibiting protein synthesis. It also binds to the bacterial 50S ribosomal subunit, causing leaking of intracellular components via the membrane. Tetracycline is broad-spectrum antibiotic, effective against Gram(+) and Gram(-) bacteria.

Description

Tetracycline is a bacteriostatic agent that acts by preventing aminoacyl tRNA from binding to the ribosome A site, thus inhibiting protein synthesis. It also binds to the bacterial 50S ribosomal subunit, causing leaking of intracellular components via the membrane. Tetracycline is broad-spectrum antibiotic, effective against Gram(+) and Gram(-) bacteria. Tetracycline is frequently used for the selection of bacteria transformed with a vector harbouring a gene conferring tetracycline resistance (Tn10), but it is also often used for the prevention of bacterial contamination of cell cultures.
