Product Notes
The COVID-19 (Catalog #AAA76123) is a Recombinant Protein produced from HEK Cells (Host protein expression may be lot-specific and can be subject to change during production, including bulk orders) and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 14-1211. It is sometimes possible for the material contained within the vial of "COVID 19 Spike S Coronavirus, 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
