When considering the incorporation of Pen-Strep into cell culture media, it is important to understand its concentration and effects on cells. Typically, the standard concentration of Pen-Strep used is 100 U/mL of penicillin and 100 µg/mL of streptomycin. This concentration is deemed effective for preventing bacterial growth without significantly impacting the growth and function of most mammalian cells. However, researchers must be cautious about long-term exposure, as prolonged use can lead to altered cell behavior, antibiotic resistance, and changes in metabolic activity.

Environmental factors, including poor air quality and high ammonia levels, may exacerbate these issues, causing irritation of the respiratory tract.
