new invention has discovered a method to stabilise an enzyme during freezing providing the enzyme in a zwitteronic buffer solution. A zwitterionic composition is useful as a surface active agent in aqueous solutions. The buffer solution has the capacity to stabilise an enzyme‚ such as glocuse oxidase‚ in a liquid state whilst providing protection if the the end solution is frozen. The zwitterionic buffer can stabalise the activity of enzymes by preventing large pH shifts during freezing.
