Histone H3 trimethyl Lys4 ELISA
Histone Modification ELISAs provide a simple, sensitive method for detecting changes in specific histone modifications from purified core histones or histones isolated by acid extraction. These kits are sandwich ELISAs that utilize a capture antibody against histone H3 and a primary antibody specifc for the modification of interest. A secondary antibody conjugated to horseradish peroxidase (HRP) and developing solutions provide a sensitive colorimetric readout that is easily quantified by spectrophotometry. The assay is performed in a convenient 96-stripwell plate, enabling low or high throughput screening.
