Saphyr system from Bionano Genomics

The Bionano Genomics Saphyr system uses a non-sequencing based optical mapping technology to analyse extremely long strands of genomic DNA. This DNA is fluorescently labelled with the new Direct Labelling (DLS) technology and is imaged after individual DNA molecules are separated in thousands of channels on a nano-fluidic chip.

With this system large structural variants including insertions and deletions, translocations and inversions at genomic scale can be analysed. A favourable method for researchers interested in for example plant trait development, domestication, or polyploidy. With high quality software and improved computational resources, assembly, scaffolding, variant calling and annotation is readily available for our customers.

This allows construction of high precision genome maps which, combined with other NGS technologies, generate exciting new possibilities to reconstruct complex genomes. The power of this combination can be found in an increase in the contiguity of the assembly, to benefit both in a practical and economical way.
