I recently picked up an MSP project and a former lab mate left some bisulfite-modified DNA samples behind.


Does anyone know if bisulfite-modified DNA expires @ -20 or -4 degrees, and if so after how long?  The kit I have doesn't say one or another and I couldn't find a clear answer online.

Depends of the kit, some can be use for 2 years and others 1-2 month.  Usually the modify DNA is store at 4C not at freezer because it may damage it.  Ask directly to the company if the protocol doesn't state expiration time.
