<unk>  (also known as<unk> icillin-streptomycin) is a mixture of<unk> icillin G and<unk> tomycin that is widely used in mammalian cell culture media to prevent bacterial contamination. The solution contains 5,000 units of<unk> icillin G (sodium salt) which acts as the active base, and 5,000 micrograms of<unk> tomycin (sulfate) (base per milliliter), formulated in 0.85% saline. In general, 50-100 units of<unk>  per milliliter of media is used to avoid contamination in cell culture. Thus, the retail product is generally 100 times more concentrated. It is recommended for use in cell culture applications at a concentration of 10 ml per liter. It is the most common antibiotic solution for the culture of mammalian cells and it does not have any adverse effects on the cells themselves. It was first introduced in 1955 in cell culture.<unk> icillin is a beta-lactam antibiotic that is effective in inhibiting Gram-positive bacteria, whereas<unk> tomycin is an aminoglycoside antibiotic which is effective against most Gram-negative bacteria.
