Description and Uses

Tetracycline is a broad-spectrum antibiotic that prevents bacterial growth by inhibiting protein synthesis. It binds to a single site in the 30S ribosomal subunit which prevents attachment of aminoacyl tRNA to the ribosomal acceptor site. It is used in cell biology as a selective agent in cell culture systems. Tetracycline is toxic to prokaryotic and eukaryotic cells and selects for cells harboring the bacterial tetR gene, which are resistant to the antibiotic.

Antibiotic substance produced by Streptomyces spp. Antiamebic; antibacterial; antirickettsial.
