It is recommended for use in cell culture applications at 10mL/L. Antibioticantimycotic solution is generally used to prevent the growth of harmful microorganisms including bacteria and fungi in cell culture media.
Application
Antibiotic antimycotic solution has been used:

• as a supplement in different types of cell culture media.

• as a component of storage solution for preserving tracheal segments harvested for subsequent experimental investigation.

Biochem/physiol Actions
Mode of Action: Penicillin acts by inhibiting bacterial cell-wall synthesis. Streptomycin inhibits prokaryote protein synthesis by preventing the transition from initiation complex to chain-elongating ribosome and causes miscoding. Amphotericin B interferes with fungal membrane permeability by forming channels in the membranes and causing small molecules to leak out.

Antimicrobial spectrum: Includes Gram-negative bacteria, Gram-positive bacteria, fungi and yeasts.
