Preparation & storage of GOPOD buffer - the booklet says to use immediately, but I need to store for later use

To prepare the GOPOD reagent two components are required.

1.    GOPOD Reagent Buffer

2.    GOPOD Reagent Enzymes

The reagent buffer is prepared by diluting to 1 L. Once diluted, this component needs to be used immediately to prepare the reagent enzymes.

The reagent Enzymes are dissolved with ~ 20 mL of the prepared buffer, mixed thoroughly and transferred back into the reagent buffer. This is now the Glucose Determination Reagent (GOPOD Reagent) and can be stored for ~ 3 months at 2-5°C or > 12 months below - 10°C.
