Product Notes
The Polyphenol oxidase ppo (Catalog #AAA1199283) is a Recombinant Protein produced from E Coli or Yeast or Baculovirus or Mammalian Cell and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 1-10aa; full length protein. The amino acid sequence is listed below: EQGVGGDDGL. It is sometimes possible for the material contained within the vial of "Polyphenol oxidase, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
