Catalog No. PR-V1281



  • Ideal for high-throughput applications
  • Achieve highly predictive results: robust Z« values greater than 0.8 in either 96 or 384-well plate formats
  • Observe minimal test compound interference: substrate used at micromolar concentration, rhodamine 110 fluorescent signal produced is much higher than the fluorescent signal given off by test compounds
  • Control peptide included: control peptide (AAF-AMC) included that is used to monitor protease activity, reduces false positive hits
  • Simplify assays: simple add-mix-read format reduces the number of plate-handling steps to fewer than that required for other phosphatase assays
  • Save time: minimal throughput time compared to the multiple steps and lengthy incubations with other phoshatase assays
  • Non-radioactive: no radioactive waste disposal and safety issues

  • The assay produces excellent Z« values (>0.7) in either 96 or 384-well plate formats and easily distinguishes known phosphatase inhibitors from other compounds
