Thawing Glycerol Stock Bacteria. • from the 5 ml culture prepared above add 0.50 ml of culture to a sterile 1.5 ml microfuge tube to 0.50 ml of sterile glycerol solution. Pipet 225 ul sterile 80% glycerol into the cryovial. The bacteria shed small piece of blank sample recovery.

Remove the cryovial containing the frozen cells from liquid nitrogen storage and immediately place it into a 37°c water bath.; The process is simple and requires screw cap microfuge tubes and sterile glycerol. • from the 5 ml culture prepared above add 0.50 ml of culture to a sterile 1.5 ml microfuge tube to 0.50 ml of sterile glycerol solution. Bacteria can be frozen using a solution of 15% glycerol. See the bacteria culture protocol for specific information. To prepare glycerol stocks, the glycerol is first autoclaved and allowed to cool.
Glycerol stock preparation • use sterile pipet tips and sterile microfuge tubes.
When liquid bacteria cultures are added to a 50% glycerol solution, the glycerol infuses into the bacterial cells, making them structurally stable and allowing them to be stored safely. If you are growing the bacteria in order to purify a plasmid, and if the glycerol stock originally came from a single colony, you can get away with reviving them in broth. Equal amounts of 30% glycerol and culture broth are mixed, dispensed into tubes and then frozen. Approximately 2 minutes or until all ice crystals have melted. However, if the bacterial strain is sensitive to glycerol, a 50% dmso stock can be used at a final concentration of 5%. Place tube where it would benefit from agrobacterium glycerol stock protocol will go about age of electrocompetent bacteria grow more than after lb agar without concerns about agar.

See the bacteria culture protocol for specific information. By the end of the 72 hour exposure period, 28.33% of the bacteria that survived freezing and thawing are still viable. Equal amounts of 30% glycerol and culture broth are mixed, dispensed into tubes and then frozen. Most of the test fungi could survive for 5 years in medium containing 10% glycerol even after alternate freezing and thawing at intervals of 6 months. Glycerol stock is a type of suspension used in laboratory settings to store bacterial cultures for extended periods of time.
