VKEY-BIO's TR-FRET assay kits utilize advanced time resolved fluorescence resonance energy transfer (TR-FRET) technology, delivering rapid, wash-free operation with exceptional sensitivity, low background, and outstanding stability. These ready-to-use kits are optimized for diverse applications including protein-protein interaction studies, biomarker detection (cytokines/cAMP), phosphoprotein analysis, hybridoma screening, and antibody quantification.
KeyTec® TR-FRET Human IL8 Detection Kit can be used to measure the expression level of Human IL8 in samples such as cell culture supernatants. This kit is a sandwich immunoassay developed based on KeyTec® TR-FRET technology, featuring simplicity, rapidity, high specificity, high sensitivity, and good reproducibility.
KeyTec® TR-FRET Human IL6 Detection Kit is designed for the quantitative determination of Human IL6 in supernatants. This assay is based on a sandwich immunoassay method using KeyTec® TR-FRET technology, offering a simple, rapid, highly specific and sensitive, as well as reproducible detection process.
KeyTec® TR-FRET Total STAT6 Kit can be used to measure the expression level of intracellular STAT6 total protein in cell lysates. This kit is a sandwich immunoassay developed using KeyTec® TR‑FRET technology, featuring simple and rapid operation, high specificity, high sensitivity, and good reproducibility.
The KeyTec® TR‑FRET Phospho‑EGFR (Y1068) Kit quantifies phosphorylated EGFR (Y1068) in cell lysates. EGFR, a receptor tyrosine kinase, upon ligand binding activates downstream MAPK/AKT/JNK pathways to promote proliferation, and is a key oncology target.
The KeyTec® TR-FRET Human TNFα assay kit is designed for quantitative measurement of Human TNFα protein in supernatant. It is based on sandwich immunoassay model and utilizes TR-FRET technology, known for its ease of use, homogeneity (no wash), low background, high sensitivity, robustness.
Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) technology combines the advantages of Time-Resolved Fluorescence (TRF) and Fluorescence Resonance Energy Transfer (FRET). Based on the TR-FRET principle, this method utilizes the long fluorescence lifetime and high stability of lanthanide elements to deliver superior performance. Our TR-FRET assay kits provide an easy-to-use, homogeneous experimental approach that eliminates the need for washing. The Time Resolved Fluorescence Energy Transfer technology ensures enhanced stability, lower background, improved signal-to-noise ratio, and greater sensitivity, making it an ideal solution for robust detection.
TR-FRET assay kits eliminate complex wash steps, simplifying protocol while delivering lab-ready consistency.
The TR-FRET assay kits deliver exceptional specificity and sensitivity, enabling reliable detection of low-abundance targets.
Designed for efficiency, our TR-FRET assay kits are optimized for high-throughput screening in 384-well formats.
VKEY-BIO's TR-FRET assay kits demonstrate outstanding batch-to-batch stability and experimental repeatability for consistent results.
