Pacific Biosciences is a biotechnology company founded in 2004 that develops and manufactures systems for gene sequencing and some novel real time biological observation. They describe their platform as single molecule real time sequencing , based on the properties of zero-mode waveguides. Their first commercial product, the PacBio RS, was sold to a limited set of customers in 2010 and was commercially released in early 2011. A new version of the sequencer called the PacBio RS II was released in April 2013. On 25 September 2013 a partnership between Pacific Biosciences and Roche Diagnostics was announced for the development of in vitro diagnostic products using the technology, with Roche providing $75 million in the deal.

Pacific Biosciences has developed a method for real-time sequencing of single DNA molecules (Eid et al., 2009), with intrinsic sequencing rates of several bases per second and read lengths into the kilobase range. Conceptually, this sequencing approach is based on eavesdropping on the activity of DNA polymerase carrying out template-directed DNA polymerization. Performed in a highly parallel operational mode, sequential base additions catalyzed by each polymerase are detected with terminal phosphate-linked, fluorescence-labeled nucleotides. This chapter will first outline the principle of this single-molecule, real-time (SMRT) DNA sequencing method, followed by descriptions of its underlying components and typical sequencing run conditions. Two examples are provided which illustrate that, in addition to the DNA sequence, the dynamics of DNA polymerization from each enzyme molecules is directly accessible: the determination of base-specific kinetic parameters from single-molecule sequencing reads, and the characterization of DNA synthesis rate heterogeneities.

The present invention is generally directed to compositions, methods, and systems for performing single-molecule, real-time analysis of a variety of different biological reactions, and for determining various characteristics of the different biological reactions. The ability to analyze such reactions provides an opportunity to study those reactions as well as to potentially identify factors and/or approaches for impacting such reactions, e.g., to stimulate, enhance, or inhibit such reactions.

Methods, devices, and systems for performing intermittent detection during analytical reactions are provided. Such methods facilitate collection of reaction data from disparate reaction times. Further, such methods are useful for reducing photo-induced damage of one or more reactants in an illuminated analytical reaction at a given reaction time. In preferred embodiments, the reaction mixture is subjected to at least one illuminated and non-illuminated period and allowed to proceed such that the time in which the reaction mixture is illuminated is less than a photo-induced damage threshold period.
