EpiSwitch™

EpiSwitchTM research and medical analysis services focus on the discovery, evaluation, validation, and monitoring of a novel class of epigenetic biomarkers known as chromosome conformation signatures ("CCSs") for use in medical testing kits, disease prediction, diagnosis, and treatment. CCSs can provide a compelling, stable framework from which changes in the regulation of a genome can be analyzed, long before the results of these epigenetic changes manifest themselves as obvious abnormalities

EpiSwitch™ medical analysis services utilize a proprietary validated industrial platform for CCS based biomarkers.

Chromosomal Conformation Capture

The packaging of chromosomal DNA plays a critical role in the epigenetic regulation of the whole genome. It ensures effective storage, access to genetic information and its regulation by the complex protein machinery utilised in gene expression. Known also as ‘gene loops’, ‘long-range chromosomal interactions’ and ‘chromatin domains’, CCSs have been recognised as an essential high-level framework of epigenetic regulation imposed across the whole genome and reflecting its fractal nature of organisation.
