Penicillin can effectively inhibit Gram-positive bacteria by interfering with bacterial cell wall synthesis. Streptomycin inhibits bacterial proliferation by binding to the 30S subunit of the bacterial ribosome and inhibiting bacterial protein synthesis, mainly acting on Gram-negative bacteria, but also effective against Gram-positive bacteria. Penicillin combined with streptomycin can prevent most bacterial contamination. This product contains Penicillin 10,000 U\/mL and Streptomycin 10 mg\/mL, and is sterilized by 0.1 μm filtration. Add 1 mL of penicillin-streptomycin mixture per 100 mL of culture medium when using. Application Fields Common antibiotics for the prevention of microbial contamination in in vitro cell culture Operation steps 1. Thaw at 4°C and mix before use. To avoid repeated freezing and thawing, it is recommended to make small portions after the first thawing and store at -20°C. 2. This product is a concentrate, please dilute and use as needed. 3. This product should not be stored at 4°C or room temperature for a long time, antibiotics will be degraded at higher temperatures. 4. If the storage conditions of double antibiotic are correct, the yellowing of double antibiotic will not affect its bacteriostatic effect, and it can be used normally. 5. After thawing, there may be insoluble precipitate, after vortexing to fully dissolve, it can be used. 6. Please pay attention to aseptic operation to avoid bacterial contamination. 7. Please wear lab coat and disposable gloves during operation. Related Information Please e-mail for the detailed characterization data.
