Maintenance of C. elegans

Caenorhabditis elegans can be frozen and stored indefinitely in liquid nitrogen (− 196 C) (Brenner, 1974). The keys to a successful freeze are using animals at the correct stage of development, the addition of glycerol to the freezing media, and a gradual cooling to -80 C. Freshly starved young larvae (L1-L2 stage) survive freezing best. Get price

where does liquid nitrogen come from.?

2006/6/29Liquid nitrogen is at a temperature of about 77 Kelvin (-196 degrees C) (-320 degrees F). It's very cold, but not that dangerous unless you do something stupid like pour a bucket of it on your head. When exposed to air at room temperature, water vapor in the air condenses just above the cold liquid nitrogen and forms a little cloud - this is what looks like fog above the liquid nitrogen.
