you see, we are going to use it for our science project,and since we don't have nitrogen, can you please give us some substitute?
PULEZ?
dry ice is easily obtainable ~will not `cool` as much ,but the basic principle is still there.
put `dry ice` in your browser to find a local supply
you could then put the dry ice and seeds in a vacuum(thermos)flask
hope this helps
In meat storage, we do quick freezing and slow thawing to kill microorganisms. In cell culture, we store cell lines by slow freezing to protect the cells. However, we resuscitate cells by rapidly raising the temperature to 37 degrees celcius. How does this process help protect our cells?
I used to do cell cultures long time ago but I no longer, I'll do my best to answer. Freezing solution usually has DMSO which is toxic to the cells. While thawing, you do it quickly at 37 or between your fingers and replace the freezing solution with culture medium (has no DMSO) to prevent excessive amounts of DMSO to enter the cells.
i really need this answer!
cryopreservation occurs when cells are frozen with liquid nitrogen until it reaches a temperature of -100 degrees C. This makes the cell slow down. it even keeps it from dying because it is so cold. Scientists replace the expanding liquid with a substance sorta like anti-freeze. this keeps the cell from growing with the liquids. ex: whne water freezes the ice expands so thats kinda what happens in a cell it breaks.
its sorta like that :)
