摘要: The present invention relates to an apparatus for conducting assays on samples and/or processing of samples. The apparatus comprises a rotatably arranged cylindrical sample holder for holding a sample at a lateral surface of the cylindrical sample holder. The cylindrical sample holder is configured to be at least partly covered by a liquid layer. The apparatus further comprises a liquid dispensing means configured to add liquid to the liquid layer, a reagent dispensing means configured to add a reagent to the liquid layer and a liquid contacting means configured to distribute liquid within said liquid layer. The liquid contacting means comprises a plate-like element flexibly assembled in relation to the cylindrical sample holder. The present invention also relates to a method for conducting assays on samples and/or processing of samples.

摘要: A method and apparatus are provided, in which an observation volume is defined by a volume where light from illumination means and a field of view of detection means overlap. The central axes of said light from the illumination means and said field of view of the detection means are non-parallel, and the sample is transported through the observation volume during imaging, preferably by rotation of a sample container holding the sample.

摘要: A sample holder (100) for an apparatus (300) configured to perform an assay at a plurality of sample sites (130) is disclosed, wherein each sample site comprises a concatemer. The sample holder comprises a rotatable body (110), a matrix layer (120) and a liquid layer arranged on the matrix layer. The plurality of samples sites are distributed in the matrix layer in both a lateral direction and a thickness direction of the matrix layer, and the rotatable body is configured to be arranged in the apparatus to be rotatable around an axis (A) while the assay is performed at the plurality of sample sites. A corresponding method (200) and apparatus (300) are also disclosed.

摘要: An apparatus for imaging a includes an light source for illuminating the sample simultaneously in a line focus or an array of foci; and a sensor for detecting photons emitted or scattered from the sample simultaneously in an array of fields of view. An array of sub-observation volumes in the sample, from which photons are emitted or scattered during imaging, is defined by the volumes in space where the line focus or array of foci from the light source overlap with the corresponding array of field of views of the sensor. A cylindrical sample holder holds the sample at a surface and is rotatably arranged such that at least a portion of the sample can be transported through at least one of the sub-observation volumes by rotating the sample holder. The apparatus can be used in a high-throughput method of imaging.
