Compared to the standard version, the High-Performance format delivers a higher signal-to-background ratio and improved sensitivity, ensuring more robust results even in challenging conditions. These enhancements make it possible to obtain reliable results on more physiological models such as primary cells, broadening the applicability of the assay for translational and advanced research. STAT3 is upregulated in various diseases, particularly autoimmune disorders, neurodegenerative diseases, or cancers, making this kit a powerful tool for therapeutic strategies by inhibiting the pathway.\u003cbr\u003e\nHTRF assays offer many advantages over other technologies:\u003c\/p\u003e\n\n\u003cp\u003eHomogeneous add-and-read format\u003cbr\u003e\nNo wash steps\u003cbr\u003e\nLow background\u003cbr\u003e\nStraightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates\u003cbr\u003e\n Stable signal, providing flexibility in readout time or size of assays\u003cbr\u003e\nHow it works\u003cbr\u003e\nHigh Performance Phospho-STAT3 (Tyr705) assay principle\u003cbr\u003e\nThe High Performance phospho-STAT3 (Tyr705) assay measures STAT3 when phosphorylated at Tyr705. Unlike Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis, or transfer. It uses two antibodies: one labeled with a donor fluorophore and the other with an acceptor. The first antibody specifically binds the phosphorylated motif on the protein, while the second recognizes the protein independently of its phosphorylation state. Protein phosphorylation enables the formation of an immune complex involving both labeled antibodies, bringing the donor fluorophore into close proximity to the acceptor and generating a FRET signal. Its intensity is directly proportional to the concentration of phosphorylated protein in the sample, allowing assessment of the protein’s phosphorylation state in a no-wash assay format.\u003c\/p\u003e\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n\n\n\n\u003cp\u003eHigh Performance Phospho-STAT3 (Tyr705) two-plate assay protocol\u003cbr\u003e\nThe two-plate protocol involves culturing cells in a 96-well plate before lysis, then transferring lysates into a 384-well low volume detection plate before the addition of High Performance phospho-STAT3 (Tyr705) HTRF detection reagents.
