Abstract:
1. A method for reducing the loss of biological activity of an enzyme in solution comprising: (a) storing an enzyme in solution for 90 minutes in an apparatus which has been made by applying a non-ionic surfactant to a hydrophobic surface of the apparatus wherein said non-ionic surfactant has (i) a hydrophilic-lipophilic balance number which is less than or equal to 5 and (ii) at least one hydrophilic element which can extend into an aqueous solution; and drying the non-ionic surfactant on hydrophobic surface of apparatus, without a step of washing with an organic solvent between the applying step and the drying step; (b) wherein storing the enzyme in the solution in the apparatus results in a reduction in loss of activity of the enzyme.
