We apply all relevant Next- and Third-generation Sequencing Technologies to get the best Results possible

Pacific Biosystems
(PacBio)

Long sequencing reads for contiguous and accurate assemblies

Pacific Biosystems® SMRT® Sequencing technology brought long-read sequencing to a level where high-quality and highly contiguous assemblies can be generated by relying solely on this technology.

Genexa uses PacBio for the following key applications:

Complete and circular prokaryotic assemblies of high accuracy (> 99.999%)
Detection of small & large scale variants
De novo assembly of metagenomes from low to moderate complexity

Contact us if you want to establish PacBio sequencing technology in your lab.

Oxford Nanopore Technologies

Super long sequencing reads, tiny sequencer and a lot of potential

Genexa uses Oxford Nanopore Technologies® for the following key applications:

Resolving very long genetic repeats as expected in some prokaryotes and in general in eukaryotes
De novo assembly of metagenomes from low to moderate complexity
Rapid taxonomic profiling of metagenomes
Rapid detection of specific organisms in your samples

Illumina sequencing

Short but highly accurate sequencing reads

Illumina® sequencing has been fully established in the genomics community for many years. Its "sequencing by synthesis" technology remains the "work horse" sequencing technology in genomics.

Genexa uses Illumina sequencing for the following applications:

Draft assemblies of single genomes & metagenomes
Error correction of assemblies based on long-read sequencing
Small-scale variant detection
Taxonomic profiling via shotgun metagenomic sequencing
