Can samples be stored in a fridge or freezer after enzyme treatment in the Total Starch Assay Kit (K-TSTA)?

We have not frozen extracts before the GOPOD step as we always complete the assay in full.

However we have stored extracts in the fridge if it is necessary to repeat one or two samples. So we would be confident in saying the extracts should be OK in the fridge for 1-2 days.
