How to store bacteria in glycerol
WebHowever, if you want to store bacteria for a longer time, you will need to establish glycerol stocks. The addition of glycerol stabilizes the frozen bacteria, preventing damage to the cell membranes and keeping the cells alive. A glycerol stock of bacteria can be stored stably at -80°C for many years. WebB. Preparation of a fresh copy (V2) of bacterial glycerol stock(s): 1. Follow instructions in Part 1 for inoculation and growth in 96-well plates and duplication of glycerol stocks to make a new glycerol copy (V2 glycerol). These newly prepared V2s are then used in inoculations for plasmid DNA isolation.
