Abstract:
A computer-implemented method for identifying a first object-of-interest is provided. The first object-of-interest includes two identifiers and a sample portion. The method includes imaging the first object-of-interest including the two identifiers. The imaging generates a first set of image data. The method further includes determining a position of the first object-of- interest in the field-of-view of an optical sensor and determining the two identifiers from the first set of image data. The method includes identifying the first object-of-interest based on the two identifiers.
Abstract:
An instrument (1000) for processing and/or measuring a biological process contains an excitation source (110), a sample holder (204), an optical sensor (118), an excitation optical system (120), and an emission optical system (125). The sample holder (204) is configured to receive a plurality of biological samples. The optical sensor (118) is configured to receive an emission from the biological samples. The excitation optical system (120) is disposed along an excitation optical path (126) and is configured to direct the electromagnetic radiation from the excitation source (110) to the biological samples. The emission optical system (125) is disposed along an emission optical path (128) and is configured to direct electromagnetic emissions from the biological samples to the optical sensor (118). The instrument further contains a plurality of filter assemblies (130, 132) configured to be interchangeably located along at least one of the optical paths. The plurality of filter components (131) includes a first filter component (138) characterized by a first optical power and a first filter (140) having a first filter function, the first filter function characterized by at least one of a first low-pass wavelength or a first high-pass wavelength. The second filter assembly (142) is characterized by a second optical power and a second filter (145) having a second filter function, the second filter function comprising at least one of a second low-pass wavelength that is different than the first low-pass wavelength or a second high-pass wavelength that is different than the first high-pass wavelength. The second optical power differs from the first optical power by an amount sufficient to at least partially compensate for an aberration introduced by the second filter (145) relative to the first filter (140).
Abstract:
A biological analysis system is provided. The system comprises an interchangeable assembly configured to accommodate any one of a plurality of sample holders, each respective sample holder configured to receive a plurality of samples. The system also includes a control system configured to cycle the plurality of samples through a series of temperatures. The system further includes an optical system configured to detect fluorescent signals emitted from the plurality of samples. The optical system, in particular, can comprise a single field lens, an excitation source, an optical sensor, and a plurality of filter components. The excitation source can be one or more light emitting diodes. The field lens can be a bi-convex lens.
Abstract:
A computer-implemented method of generating a digital polymerase chain reaction (dPCR) result is provided. The method includes detecting a first set of emission data from a plurality of samples, each included in a sample region of a plurality of sample regions, at a first time during an amplification period. The method further includes determining a positive or negative amplification determination for each sample of the plurality of samples based in part on the first set of emission data. A dPCR result is generated based on the positive or negative amplification determinations for the plurality of samples.
