TR-FRET Assays

TR-FRET (Time-Resolved Fluorescence Energy Transfer) is a special form of FRET (Förster Resonance Energy Transfer) in which the long-lived emission fluorophores are used as donors. Sandwich TR-FRET immunoassays for semi-quantitative detection enable the examination of phosphorylation events in cellular signaling pathways. We offer high quality TR-FRET Assay Kit alternatives at an outstanding price.

• Unlike other TR-FRET kits, we include a positive control in every kit to allow results you can depend on.
• Our Phospho-Protein Kits enable the detection of proteins phosphorylated at defined residues.
• Total-Protein Kits allow the detection of total protein in a sample and can be used to normalize your data obtained with the Phospho-Kits.
• The Phospho- and Total Protein Kits are designed for simultaneous measurement of two proteins (phosphorylated and total) in separate wells from the same cell lysate using a single kit.

Our kits come in convenient sizes of 100 and 500 points for 69 key targets.
