Penicillin-Streptomycin Solution (100×), Sterile

Penicillin-streptomycin solution, also known as Pen-Strep, is the most commonly used combined antibiotic solution against both gram-positive and gram-negative bacteria. Penicillin can directly interfere with the synthesis of bacterial cell wall and indirectly alter the cell wall by triggering enzymatic reactions. Streptomycin can bind to the 30S subunit of the bacterial ribosome, and inhibit the synthesis of bacterial protein, ultimately leading to the death of susceptible bacteria. The solution is used to supplement cell culture media to control bacterial contamination.
