Pipetting Samples
BreakSight, Inc provides services that label, retrieve, and locate broken DNA ends in actively replicating cells experiencing DNA damage to find patterns associated with breakage.
DDsite Logo - DDsite is our platform where we utilize our BrITL assay and perform NGS to capture and sequence DNA breaks occurring in cells from customer-applied treatments.

BrITL - Retrieval of DNA double-strand break sites across the genome from cells exposed to treatment(s) that induces DNA damage during proliferation
