Carbenicillin, Disodium Salt is a semi-synthetic penicillin antibiotic effective against Gram-positive and Gram-negative bacteria. It is commonly used in molecular biology, genetic engineering, microbiology, and cell culture as a selective agent in plasmid-based cloning. It inhibits bacterial cell wall synthesis, allowing selection of cells expressing Carbenicillin resistance genes. This antibiotic prevents bacterial contamination in cell cultures and supports isolation and maintenance of resistant strains. Key features include broad-spectrum activity and stability in aqueous solutions.
