Analytical system with accurate positioning of multiwell plates

The present disclosure relates to an analytical system with at least three components: a multiwell plate on which the wells are included in an optically transparent area; a frame holding the multiwell plate close to its edge while permitting the plate a certain extent of freedom of movement; a baseplate to which the multiwell plate, but not the frame is firmly fixed via a docking mechanism, such that different expansion of plate and frame can be compensated. A second aspect described herein relates to a method of docking a corresponding multiwell plate held by a frame to a baseplate and subjecting the multiwell plate to a step of a biological or chemical assay within this arrangement.

20220268778 · 2022-08-25 ·

A method of analyzing and/or sorting selected cells or other biological components, for example for cell-based therapy, includes sampling a sample with an open end of a probe to obtain a fluid stream with the sample in it. The probe with the open end also has a fluid supply to convey fluid to the open end, and a fluid exhaust to convey the fluid stream away from the open end. The method then includes conveying the fluid stream to a flow cytometer and analyzing the fluid stream by flow cytometry; and/or separating it into at least two components. An apparatus with the probe connected to the flow cytometer may support this method. The method can provide for sampling of multiple samples efficiently, in particular to select cells for cell-based therapies.

MULTI-PLANE MICROARRAYS

An array including a solid support having a plurality of contours along its exterior surface. A first subset of contours is positioned along the exterior surface of the solid support to form a first pattern of features and a second subset of contours is positioned along the exterior surface to form a second pattern of features. The contours of the first subset are juxtaposed with the second subset along the exterior surface, whereby the first and second patterns form an interleaved pattern. The features of the first pattern occur at a first elevation z.sub.1 and the features of the second pattern occur at a second elevation z.sub.2. The features of the first pattern are configured to attach analytes at a different elevation relative to analytes attached to the features of the second pattern.
