Porvair Sciences has announced the addition of the novel Chromatrap chromatin immunoprecipitation (ChIP) assay range to its portfolio of products for epigenetics. Developed in conjunction with Department of Life Sciences at University of Swansea, UK, Chromatrap uses a solid phase porous polymer functionalized with protein A, allowing the chromatin capture to be more efficient than bead based methods. The Chromatrap spin column approach offers significant advantages compared to methods based on sepharose or magnetic beads, which involve many steps of separation, pipetting and re-suspension. Independent tests with Chromatrap demonstrate levels of DNA pull down up to 25 times higher than with traditional bead based procedures, excellent DNA enrichment with signal-to-noise ratios typically 2 to 3 times better than competing procedures and top performance even with samples as small as 50ng or as much as 3,000ng chromatin per immunoprecipitation.
