Rapid methods have secured a foothold within the pharmaceutical industry. However, we continue to evolve our technologies to meet the increasing demand of modern medicines. One of the drawbacks for using metabolic by-products as an indicator of microorganism growth is the risk of poor differentiation between biological signals from the product and microbial metabolites.A new assay was designed to deal with a higher background signal. By utilizing a biochemical ATP-depletion reagent, coupled with utilizing microbial adenylate kinase to enhance ATP production, a more refined, flexible assay is available for rapid sterility testing. I present evidence demonstrating the reliability of modern ATP bioluminescence assays for testing biological products. Data graphs will include: Diagram of ATP depletion/AK-ATP enhancement at the cellular level.Case studies of Applicability of an ATP-depletion reagent User eliminates the need for low-ATP sterility media (use any media supplier you want)Reduction of residual signal from a biologically derived product.3-way Equivalence/LOD data amongst 1) Compendial Sterility 2) ATP Bioluminescence 3) ATP Bioluminescence with background depletion.
