Leibovitz’s L-15 Culture Medium

Leibovitz ‘s L – 15 by phosphate buffer system of culture medium and the free base of amino acids, rather than the traditional sodium bicarbonate buffer system, at the same time, with galactose and sodium pyruvate instead of glucose can prevent the formation of acidic metabolic by-products, help maintain the stability of the nutrient solution PH, suitable for use in a non CO2 equilibrium cell culture environment.


Leibovitz’s L-15 culture medium is suitable for the culture of monkey kidney cells and HEP-2, the isolation of primary cells (e.g. embryonic and adult tissues), the culture of a variety of viruses, and the culture of neurons.

Penicillin-streptomycin Solution

Penicillin-streptomycin solution, also commonly referred to as “dual antibiotics”, is the most commonly used antibiotic in in vitro culture to prevent microbial contamination, in which penicillin interferes with bacterial cell wall synthesis and is particularly effective against Gram-positive bacteria, while streptomycin inhibits bacterial protein synthesis by binding to the 30S subunit of the bacterial ribosome and is particularly effective against Streptomycin binds to the 30S subunit of the bacterial ribosome and inhibits bacterial protein synthesis, which is effective against both Gram-negative and Gram-positive bacteria, but is particularly effective against Gram-negative bacteria. The combination of penicillin and streptomycin can prevent most of the bacterial contamination.

This product contains amino acids, vitamins, inorganic salts and many other components required for multi-culture of cells, but does not contain proteins, lipids or any growth factors, so the product should be used with serum or serum-free additives.
