ABSTRACT:
The present invention relates to systems for the vitrification of a biological specimen. The systems employ a transfer instrument such as a loop, containing a base medium that includes a cryoprotectant. The biological specimen which has undergone vitrification may be stored for a period of time, and then thawed at a later date. The thawed biological specimen remains viable. Preferred biological specimens according to the present invention are developmental cells.
