Freezing of Protozoa (Toxoplasma)protozoa
Posted 13 December 2011 - 05:56 AM
Freshly thawed parasites have very low viability (10%~), I realized gradual freezing is important.
But my lab does not have the machine (for gradual freezing -1oC per minute). Is there other way to achieve gradual freezing ?
Thanks in advance for the help.
Please advise with your professional opinion.

This slow freezing is not as effective than controlled gradual freezing, but the cells should survive better this way than putting them straight to -80°C.....

I just thaw normally like how to thaw cells.. but u have to infect the toxo immeadiately into mice intraperitoneally.. cos for me.. reinfection in cells doesnt work at all.. hope it works!!
