Histone H4 function is dependent on its acetylation state (1 acetyl group per lysine) at several sites (Lys5, Lys8, Lys12, and Lys16) on the N-terminal tail. The mis-regulation of histone acetylation is closely associated with cancer initiation and progression, making histone acetylase and deacetylase enzymes promising drug targets.\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\nTotal Histone H4 assay principle\u003cbr\u003e\nThe Total Histone H4 assay measures Histone H4 levels in cells. Unlike Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis, or transfer. The assay uses 2 antibodies, one labeled with a donor fluorophore and the other with an acceptor. Both antibodies are highly specific for a distinct epitope on the protein.\u003cbr\u003e\nIn the presence of Histone H4, this enables an immune-complex formation involving both labeled antibodies, and which brings the donor fluorophore into close proximity to the acceptor, thereby generating a FRET signal. Its intensity is directly proportional to the concentration of total protein present in the sample.\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\u003eTotal Histone H4 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 Total Histone H4 HTRF detection reagents.
