13. Stability of the plasmid?

The lyophilized plasmid is stable at -20°C for at least 1 year. Plasmid dissolved in TE is stable for at least 6 months at -20°C or 4°C. Plasmid dissolved in water is stable for at least 6 months at -20°C in the absence of nucleases. Please ensure the water used is at neutral pH to avoid depurination.
