It has been reported that an aqueous solution of this material stored overnight in a borosilicate glass vial leads to the formation of ouabain-borate complexes.
It is therefore recommended that this material is stored in a plastic vial and any contact with borosilicate glass is minimised.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
