Penicillin-Streptomycin Solution

Penicillin-Streptomycin Amphotericin Solution — Penicillin-Streptomycin Amphotericin Solution is a concentrated antibiotic–antimycotic supplement for tissue culture that helps reduce bacterial and fungal contamination while propagating mammalian cells.

Manufacturer: MOLEQULE-ON (Auckland, New Zealand). Supplier: EMDA. Size: 100 mL.

• Composition (stock): Penicillin G 10,000 U/mL; Streptomycin sulfate 10 mg/mL; Amphotericin B 25 µg/mL. (mpbio.com)
• Formulation & format: Sterile, filtered aqueous solution supplied as a concentrated stock for in-laboratory dilution.
• Recommended use: Add to complete cell culture medium at the manufacturer's recommended dilution (commonly 1:100) to achieve typical working concentrations (approx. 100 U/mL penicillin, 0.1 mg/mL streptomycin, 0.25 µg/mL amphotericin B).

• Storage & handling: Protect from light, avoid repeated freeze–thaw cycles and aliquot for long-term storage (store frozen at -20°C when possible; follow the product COA for specific stability). (oricellbio.com)
• Key benefits & notes: Broad activity against gram-positive and gram-negative bacteria plus yeasts/fungi; convenient 100 mL stock for routine laboratory use. Use judiciously—antibiotics/antimycotics can mask low-level contamination and may affect sensitive cell lines, so limit use or remove once cultures are established. Intended for research use only, not for diagnostic or clinical applications. (atcc.org)
