Is the “Best By” date the expiration date for the product? Will the product still work after that date?

Our products can be expected to perform at optimal levels up until the printed "Best" by date on the vial when stored under the recommended conditions. Many of our products will work well after the best by date has passed, however we cannot guarantee their optimal performance after this date. 

We routinely quality control test our antibodies based on half the shelf life of the product. Our best by dates are based on the date of packaging and may be extended for the same lot, based on the product passing recent QC testing.
