For many of our antibodies, freezing at -20oC or -80oC in small aliquots is the optimal storage condition. Aliquotting minimizes damage due to freezing and thawing, as well as contamination introduced by pipetting from a single vial multiple times. Aliquots are to be frozen and thawed once, with any remainder kept at 4oC.I quickly take you through how to draw the Lewis Structure of N3- (Azide Ion) .
