Notes
All stocks solutions should be filter sterilized, not autoclaved!
Stocks dissolved in EtOH do not need to be filtered
All stocks should be stored at -20°
All plates and media with antibiotics should be stored at 4°
γ/δ means g/L or mg/mL
Dry antibiotic powders should be stored at 4° in a humidity-free container
- Molecular Cloning appendix A2.6 (Vol 3)
