It enables calculation of the affinity of the XIAP BIR3 Red Ligand for XIAP BIR3 protein in the presence of the targeted protein of interest. The Kd of HTRF XIAP BIR3 Red Ligand for XIAP protein, in absence and presence of the targeted protein, enables an accurate analysis of the cooperative effect assessed with the HTRF XIAP BIR3 binding kit.\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\nStable signal, providing flexibility in time of readout or size of assays\u003cbr\u003e\nHow it works\u003cbr\u003e\nHTRF XIAP ligand binding assay principle on the XIAP BIR3 binding domain\u003cbr\u003e\nHTRF XIAP BIR3 Red Ligand binding is detected in a direct binding assay format, using an anti GST-Terbium Cryptate antibody which binds to GST-tagged Human XIAP BIR3 domain. When the dyes are in close proximity, the excitation of the donor with a light source (laser or flash lamp) triggers a Fluorescence Resonance Energy Transfer (FRET) towards the acceptor, which in turn fluoresces at a specific wavelength (665 nm) (Image A). The specific binding signal is calculated by subtracting the non-specific binding signal from the total signal, enabling Kd determination for the HTRF XIAP BIR3 Red Ligand (Image B).\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  \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\u003eHTRF XIAP BIR3 Red Ligand binding assay protocol\u003cbr\u003e\nSaturation binding experiments of HTRF XIAP BIR3-Red Ligand can be run in 384-well plates by dispensing 5 µL of Diluent 9 buffer (for Total binding) or XIAP BIR3 Binding standard (for non specific binding). Then 5 µL of PROTAC Binding Buffer 2 (for reference) or the targeted protein diluted in PROTAC Binding Buffer 2 (for cooperativity studies) are added, followed by 5 µL of GST-tagged XIAP BIR3 protein. Finally, 5 µL of a pre-mixed solution of HTRF XIAP BIR3-Red Ligand and Anti-GST Tb cryptate antibody are added.\u003cbr\u003e\nThe HTRF Ratio is measured after 2 hours of incubation at room temperature Automation Compatible-Yes\u003cbr\u003e\nBrand-HTRF\u003cbr\u003e\nDetection Modality-HTRF\u003cbr\u003e\nProduct Group-Fluorescent Reagent\u003cbr\u003e\nShipping Conditions-Shipped in Dry Ice\u003cbr\u003e\nTechnology-TR-FRET\u003cbr\u003e\nTherapeutic Area-Inflammation Neuroscience Oncology \u0026amp; Inflammation\u003cbr\u003e\nUnit Size-1 unit\u003c\/p\u003e","brand":"Revvity","offers":[{"title":"Default Title","offer_id":46775323918505,"sku":"64XIAPFLRED","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/revvity-64xiapflred","provider":"Iright","version":"1.0","type":"link"}
