NEW YORK (GenomeWeb News) – Roche NimbleGen said today that it has aligned its chromatin immunoprecipitation-on-microarrays (ChIP-chip) with Sigma Aldrich's GenomePlex whole-genome amplification technology, and the companies will co-market the technologies together.

Researchers can use the two platforms together to study the genome for epigenetic interactions between DNA and DNA-binding proteins to find out what regions are transcriptionally active or repressed, and the mechanisms that regulate these processes, Roche said.
