Richard, We use the COX2 for Cayman chemicals and have never had any issues with it. It stores at -20 once you rehydrate and aliquot. Bernice

If this holds up, get ready to start doing a lot of COX-2 IHC. Does anyone have a good mAb to COX-2 that works on formalin-fixed, paraffin-embedded tissue that they would recommend? Thank you.
