Catalog Number: (45000-650) Supplier: Corning. Description: This product is a mix of the antibiotics Penicillin (5,000 IU) and Streptomycin (5,000 μg/ mL) in a 50-fold working concentration. In contrast, brief treatment with streptomycin failed to affect subsequent killing by penicillin. These findings suggest that the synergism of penicillin with streptomycin depends on the damaging effect of penicillin on the cell membrane, which promotes further damage by streptomycin and increases its subsequent access to intracellular sites.
