产品描述： The antibiotics Penicillin, Streptomycin, and Neomycin 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 fungus Penicillium and acts by interfering directly with the turnover of the bacteria cell wall and indirectly by triggering

the release of enzymes that further alter the cell wall. Streptomycin was originally purified from Streptomyces griseus and

Neomycin from Streptomyces fradiae. Streptomycin and Neomycin act by binding to the 30S subunit of the bacterial

ribosome leading to inhibition of protein synthesis and death in susceptible bacteria. We offer a variety of antibiotics and

antimycotics for cell culture applications.
