Introduction
Penicillin-Streptomycin-Amphotericin B Solution, is a frequently used antibiotic solution in in vitro culture. It is primarily used to prevent microbial contamination in in vitro cultures and is typically prepared as a 100X concentrated stock solution. Penicillin interferes with the synthesis of bacterial cell walls and is effective against Gram-positive bacteria. Streptomycin binds to the 30S subunit of bacterial ribosomes, inhibiting bacterial protein synthesis, and is effective against both Gram-negative and Gram-positive bacteria, especially Gram-negative bacteria. Amphotericin B binds to ergosterol in fungal cell membranes, causing membrane damage, increased permeability, leakage of intracellular substances, and disruption of normal metabolism, thereby exerting an antifungal effect. However, it is ineffective against bacteria. The combination of Penicillin, Streptomycin, and Amphotericin B can prevent the vast majority of bacterial and fungal contamination.
