Until 2003 known as Cistem Molecular Corporation, Genpathway, Inc. provided ChIP (chromatin immunoprecipitation) technologies and services that identify and analyze gene-expression mechanisms and their biological pathways to drive discovery and testing of novel pharmaceuticals, biomarkers, and diagnostic tests. Specializing in providing complete service solutions for genome-wide analysis of epigenetic events, including DNA methylation, histone modification and transcriptional regulation, Genpathway's assays analyze gene transcription, gene regulation by transcription factors and co-regulators, and the corresponding genetic pathways. In November 2010, the firm was acquired by the German firm Active Motif which provides innovative fluorescent reagents for Life Science research applications.
