Succinimidyl esters (SE, also known as NHS esters), such as our amine-reactive dyes.If your institution requires you to document expiration date based on date of manufacture for reagents, please contact for assistance.Ĭhemical products with special stability considerations: If you have a Biotium compound that has been in storage for longer than one year that you wish to use, we recommend performing a small scale positive control experiment to confirm that the compound still works for your application before processing a large number of samples or precious samples.Įxpiration date based on date of manufacture (DOM)

Fluorescent compounds should be protected from light for long term storage. Storage conditions can be found on the product information sheet or product safety and data sheet, material safety data sheet, and on the product label. However, the majority of these products are highly stable for many years, as long as they are stored as recommended. If you have an older conjugate in storage that you wish to use, we recommend performing a small scale positive control experiment to confirm that the product still works for your application before processing a large number of samples or precious samples.įor lyophilized antibodies, we recommend reconstituting the antibody with glycerol and antimicrobial preservative like sodium azide for the longest shelf life (note that sodium azide is not compatible with HRP-conjugates).īiotium guarantees the stability of chemicals, dyes, and gel stains for at least a year from the date you receive the product. Antibodies and other conjugates often are functional for significantly longer than the guaranteed shelf life.

The guaranteed shelf life from date of receipt for antibodies and conjugates is listed on the product information sheet. If you have an older kit in storage that you wish to use, we recommend performing a small scale positive control experiment to confirm that the kit still works for your application before processing a large number of samples or precious samples. Kits often are functional for significantly longer than the guaranteed shelf life. Some kits have an expiration date printed on the kit box label, this is the guaranteed shelf life date calculated from the day that the product shipped from our facility. The guaranteed shelf life from date of receipt for bioscience kits is listed on the product information sheet.
