Genome maps are generated from massively parallel, single-molecule visualization of extremely long DNA without amplification, providing long-range contiguity and eliminating PCR bias. DNA molecules labeled, using either the Direct-Label-Stain method or Nick-Label-Repair-Stain method, contain sufficient sequence-uniqueness to unambiguously map to a reference or assemble de novo. The result is a comprehensive, accurate, unbiased view that provides unique insights into genome structure and opens the door to countless applications, both with and without sequencing.
