Reagents available for laboratory, research, and clinical use are often acquired with a specified expiration date. Yet, many are not, depending on the manufacturer and reagent type. What a manufacturer does is frequency determined by how they label the product.
The U.S. Ricd and Drug Administration [FDA] has defined categories by which reagents can he labeled based on their “intended use”. individual reagents (e.g., antibodies) intended for clinical diagnostic laboratory use will be labeled as an in Vitro Diagnostic [IVD] or Analyte Specific Reagent [ASR]. Under these categories, specified expiration dates must be supported by stability testing which establishes the product shelf life.
