Storing eluted DNA and RNA
DNA is more forgiving than RNA once eluted. Choose TE or water, plan aliquots and freeze-thaw, and treat humidity and power cuts as storage risks.

Storing proteins without inventing a stability claim
Store proteins as aliquots, record the conditions you used, and follow the source. There is no universal stability claim that fits every polypeptide.
