TNF alpha acts as a chemoattractant and promotes infiltration and activation at inflammation sites. TNF alpha is involved in several cancer types due to its ability to promote angiogenesis and cell proliferation, as well as to inhibit apoptosis.\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\nPrinciple of the HTRF HP human TNF alpha assay\u003c\/p\u003e\n\n\n\u003cp\u003eCell supernatant, sample, or standard is dispensed directly into the assay plate for the detection by HTRF reagents (384-well low-volume white plate or Revvity low-volume 96-well plate in 20 µl). The antibodies labeled with the HTRF donor and acceptor are pre-mixed and added in a single dispensing step, to further streamline the assay procedure. The assay can be run up to a 1536-well format by simply resizing each addition volume proportionally.\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\u003cp\u003eAssay data analysis\u003cbr\u003e\nThe 4 Parameter Logistic (4PL) curve is commonly recommended for fitting an ELISA standard curve. This regression enables the accurate measurement of an unknown sample across a wider range of concentrations than linear analysis, making it ideally suited to the analysis of biological systems like cytokine releases.
