Abstract:
A method for sequencing a target polynucleotide includes detecting a first series of nucleotide incorporations complementary to at least a portion of the target polynucleotide. The first series of nucleotide incorporations forms a first complementary polynucleotide. The target nucleotide is secured to a substate disposed in a sequencing zone of an assembly. The method further includes moving the substrate to which the target nucleotide is secured to a templating zone of the assembly; removing the first complementary polynucleotide when the substrate is disposed at the templating zone of the assembly, the target polynucleotide remaining secured to the substrate; following the removing, moving the substrate to which the target polynucleotide is secured to the sequencing zone; and detecting a second series of nucleotide incorporations complementary to at least a portion of the target polynucleotide, the second series of nucleotide incorporations forming a second complementary polynucleotide.
Abstract:
A method, computer program product, and system are provided to calibrate a sensor array with a plurality of sensors. Preferably, the sensor array consists of a plurality of ISFETs which are in fluid communication with a reference electrode. A particular reference voltage is determined, which depends on the maximum value of the overall average gain of the sensors in an array, but also on a maximum number of sensors available for the measurement. The method includes sweeping a voltage of the reference electrode from a first voltage to a second voltage. The output voltage of each of the plurality of sensors is monitored at one or more voltages within the first and second voltages. The gain of each sensor at each of the one or more voltages is determined. An overall average gain of the plurality of sensors is calculated at each of the one or more voltages. Further, an acquisition window for the sensor array is determined. The acquisition window includes a maximum distribution of sensors that provides a maximal overall average gain at a particular reference electrode voltage.

A method for user guided initiating of an instrument includes receiving a run plan via a user interface of the instrument; indicating on the user interface, based on the run plan, a consumable to be provided to the instrument; detecting the presence of the consumable using a vision system; and indicating the presence of the consumable via the user interface.
Abstract:
A method, a computer program and an apparatus for measuring a waveform associated with a chemical event occurring on an ISFET sensor array. The waveform includes at least one region associated with expected measured values and at least one region associated with unpredictable measured values. First frame averaging is applied to at least one region associated with the expected measured values. Second frame averaging is applied to at least one region associated with the unpredictable measured values. The second number of frames used for averaging is less than the first number of frames. By the variable frame averaging the amount of stored data can be reduced.
