货品编号： thermo.15140148 品牌：thermo 品名：Penicillin-Streptomycin (10,000 U/mL) 规格：20 mL 产品描述：

The antibiotics penicillin and streptomycin are used to prevent bacterial contamination of cell cultures due to

their effective combined action against gram-positive and gram-negative bacteria. Penicillin was originally

purified from the fungi Penicillium and acts by interfering directly with the turnover of the bacterial cell wall and

indirectly by triggering the release of enzymes that further alter the cell wall. Streptomycin was originally purified

from Streptomyces griseus. It acts by binding to the 30S subunit of the bacterial ribosome, leading to inhibition

of protein synthesis and death in susceptible bacteria. This solution contains 10,000 units/mL of penicillin and

10,000 µg/mL of streptomycin in a 10 mM citrate buffer (for pH stability).
