AMP PNP (adenylyl-imidodiphosphate) is a non-hydrolyzable analog of ATP. It can inhibit fast axonal transport and promote interactions between membranous organelles and microtubules [1]. AMP-PNP acts as a competitive inhibitor for most ATP-dependent systems, inhibiting a variety of ATP-hydrolyzing enzymes such as DNA topoisomerase II, SV40 large T antigen helicase, and several kinases. It also blocks ATP-sensitive, calcium-dependent potassium channels [2-4]. AMP-PNP can be used for the preparation of nucleotide solutions [5], dual-polarization fluorescence detection, actin cytoskeleton preparation for flow cells [6], and cascade binding reactions [7]. However, AMP-PNP is highly unstable under acidic conditions and rapidly hydrolyzes into phosphamide and inorganic phosphate.
