Penicillin G was one of the first and safest antibiotics used in cell culture. It acts by inhibiting bacterial cell wall synthesis. Traditionally it has been used in combination with streptomycin for broader coverage of Gram-negative and Gram-positive bacteria. Due to its long-time use in laboratories, the newer combination of Penicillin G and Gentamicin (Pen-Gent, catalog #400-129) is more often recommended to combat organisms resistant to streptomycin. Recommended concentration is 100 units/mL. Penicillin G has no activity against fungi.
