Single molecule mapping OpGen making slow progress 2

In contrast to BioNano Genomics, who is starting commercialization with early access customers now and full commercial launch in the Spring of 2013, OpGen launched the Argus™ Optical Mapping system in the summer of 2010. Their customers use this system for microbial strain mapping, mainly for infectious disease research or […]


Measuring Nanopore Signals – a Practical Challenge for DNA Sequencing 1

This past week I attended the Cambridge Healthtech Institute’s “Applying Next Generation Sequencing” meeting in Providence R.I. Attendance was down which is an indicator of the maturity of NGS technology, constrained travel budgets, or an oversupply of NGS conferences, and probably a combination of all three.


Single Molecule Sequencing – Pacific Biosciences and their method

In previous posts I covered the basics of next-generation sequencing – library preparation, template preparation, and the sequencing methodology itself, whether by pyrophosphate detection, single base extension with reversible terminators, or probe addition by ligation. And single molecule sequencing’s attractiveness as a technology has been covered here, but here I’ll […]


Oxford Nanopore, the first nanopore-based sequencing technology

Oxford Nanopore, based in Oxford U.K., made a remarkable announcement that surprised many in February’s AGBT meeting in Marco Island. A GridION and MiniION single-molecule sequencers were announced, promising 15 minute runtimes, no sample preparation, and a disposable USB-stick sequencer for $900 (in the case of the MiniION), with 50kb […]
