ChIP Sequencing

ChIP-seq is a powerful method to map transcription factor binding sites and histone modification status on a genome-wide scale. This technique is a combination of chromatin immunoprecipitation assays with sequencing.

Main steps in the ChIP-seq include cross-linking a protein to chromatin, shearing the chromatin, using a specific antibody to precipitate the protein of interest with its associated DNA, reverse cross linking and finally purifying the associated DNA fragments.

Chip Sequencing Technique

Every sample is precious, and data integrity is paramount. We communicate with our customers at every stage of the sequencing process, to ensure that they receive the maximum value out of every sample.

We also recognize that the value our customers get is not in the sequencing alone; it’s the technologies within the sequencing. MedGenome is one of the few genomics research companies that provides turnkey solutions to our customers, offering robust bioinformatics services alongside NGS sequencing.
