| Description: | The TR-FRET Adapta Universal Kinase Assay Kit was purchased from Invitrogen Corporation (Carlsbad/CA, USA) (Cat. No. PV5099). The kit contains the following reagents: Adapta Eu-anti-ADP Antibody (Europium labeled anti-ADP antibody in HEPES buffered saline, Cat. No. PV5097), Alexa Fluor 647-labeled ADP tracer (Alexa Fluor 647-labeled ADP tracer in HEPES buffered saline, Cat. No. PV5098), proprietary TR-FRET dilution buffer pH 7.5 (Cat. No. PV3574).PIK3CD substrate Phosphatidylinositol was obtained from Invitrogen (vesicules consisting of 2 mM PI in 50 mM HEPES pH7.5; Cat. No. PV5371). PIK3CG substrate Phosphatidylinositol-4,5-bisphosphate (PIP(4,5)2 was obtained from Invitrogen (PIP2:PS large unilamellar vesicules consisting of 1 mM PI P2: 19 mM PS in 50 mM HEPES pH7.5, 3 mM MgCl2, 1 mM EGTA; Cat. No. PV5100).Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) is a technology based on energy transfer between two adjacent dyes, from an excited electron in one dye (the donor) to an electron of an adjacent dye (the acceptor) through resonance, then released as a photon. This energy transfer is detected by an increase in the fluorescence emission of the acceptor, and a decrease in the fluorescence emission of the donor. TR-FRET assays for protein kinases use a long-lifetime lanthanide Terbium or Europium chelates as the donor species which overcome interference from compound autofluorescence or light scatter from precipitated compounds, by introducing a delay after excitation by a flashlamp excitation source. |
