Reviving Glycerol Stock - iGEM
WebTo prepare a frozen stock culture, add 100 µL of the diluted, transformed cells containing the pGEX DNA to 1 mL of LBGA medium and incubate for 30 min at 37 °C with shaking at 250 rpm. After incubation, add 200 µL of sterile 80% glycerol and mix with a pipette tip. Store at −70 °C.

When frozen with glycerol, however, the glycerol alleviates the harmful effects caused by ice crystals in bacteria. Reviving your bacterial culture from glycerol stocks allows you to readily use your stored sample again. how to spell conchins
