Storage and Handling

The material is supplied as a lyophilized (freeze-dried) powder. As a laboratory reagent, lyophilized peptide is generally stored desiccated and protected from light, with long-term storage commonly at -20C or below and short-term working material at 2C to 8C. For laboratory work the powder is solubilized in a solvent chosen for the intended in vitro application. These notes describe general handling of the material as a research reagent. They are not instructions for use in humans or animals.

Ordering, Shipping and Returns

An account is required to purchase, and every order requires confirmation of research use. Orders ship by UPS or FedEx with tracking; shipping options and rates are shown at checkout. Payment is by card or Zelle. Because product integrity cannot be confirmed once a research material leaves our control, returns are limited to unused, unopened products as set out in the terms and conditions.

Testing and Verification

Every peptide batch Nocap Research lists is tested by an independent laboratory for identity, purity and content, and each certificate carries a lot number and a lab certificate number you can verify with the lab. See how we test, browse all current certificates, or use the CoA checklist to review any supplier's paperwork.
