FKBP Functional PPIase Assay

  • A number of FK506 binding proteins (FKBPs) have been identified; assays are available for human FKBP12, 51 and 52.
  • Uses relevant recombinant FKBP and substrate Succ-ALPF-pNA
  • Measures cis/trans isomerisation kinetics of substrate using UV/Vis spectrophotometer
  • Uses LiCl/Trifluoroethanol. Li+ ion holds substrate in 60% cis conformation
  • Ki values obtained (6pt in duplicates)
  • Can be performed with and without additives (detergent/salt)
