Product Storage Recommendations
Optimal storage ensures retention of antibody activity over time. For immediate use, short term storage at 4°C up to two weeks is recommended.  For long term storage, divide the solution into volumes of no less than 20 ul for freezing at -20°C or -80°C.  The small volume aliquot should provide sufficient reagent for short term use.   Freeze-thaw cycles should be avoided.  For concentrate or bioreactor products, an equal volume of glycerol, a cryoprotectant, may be added prior to freezing.
