Heat sensitive biological materials may be freeze-dried without affecting their potency. The dried materials may be stored for years at room temperature without loss of their original characteristics.
The freeze-dried material may be transported and shipped in small containers, and no provision is necessary for refrigeration enroute.
Bacterial growth and enzyme action do not take place in freeze-dried products and proteins do not coagulate. Oxidation of many materials such as hemoglobin and vaccines is completely prevented when drying and sealing is done under high vacuum.
