ou have bought a new reagent, on the data sheet it says “stable at 4°C for 1 month, for long-term storage up to 1 year, store at -20°C” and “avoid repeated freeze thaw”. You don’t think you will use the whole vial in the next month, what should you do?* Aliquot into 20 tubes of equal volumes, label the tubes and store in a lab freezer. Store at 4°C for the first month and then aliquot whatever is left Tell the technical team or lab mates to arrange aliquoting and storage Calculate how much you will use in each experiment and aliquot the reagent into thoseamounts into labelled tubes and store in a labelled container in a lab freezer
