Abstract: Disclosed are various embodiments related to automated cellular passaging of spheroids, tumoroids, organoids and/or other multi-cellular bodies. Organoids can be cultured in a hydrogel that is disposed in a well unit of a microwell plate. The well unit includes a primary well section that is fluidly connected to a secondary well section via at least one channel, and the hydrogel is disposed in the primary well section of the well unit. The hydrogel is dissipated into hydrogel fragments, thereby separating the organoids from the hydrogel. The hydrogel fragments are removed from the well unit, while the organoids remain in the well unit. The remaining organoids are broken into organoid fragments and corresponding debris. A fresh culture environment is created using the organoid fragments.

Abstract: Disclosed are various embodiments for growing, culturing, monitoring, and analyzing embryoid bodies, fused embryoid bodies, spheroids, organoids, or other multi-cellular bodies in a microwell structure formed in one or more wells of an assay and culturing microplate. Hydrogel deposited into a well of the microplate and supported by a support ledge and the bottom surface of the well is molded into a microwell structure using a mold insert tool. In some examples, channels can be formed in the bottom of the microwell structure to allow for an exchange of fluid between a primary well section and a secondary well section of the well. The bottom surface of the assay and culturing microplate is optically transparent and gas-permeable.

Abstract: Disclosed are various embodiments for growing, culturing, monitoring, and analyzing embryoid bodies, fused embryoid bodies, spheroids, organoids, or other multi-cellular bodies using a system of microplates. Different types of microplates are designed to be used during the various stages of growing and culturing of cells to form embryoid bodies, fused embryoid bodies, spheroids, organoids, or other multi-cellular bodies. The different microplates are designed to mate with one another to allow for the transfer of cells from wells in one plate to wells in the other plate. An assay plate includes an array of perfusable units that include a supply well that is in fluid communication with a culture well to allow for an exchange of fluid.

Abstract: A light-field microscope includes a light-sheet focusing device configured for outputting illumination light as a light sheet, and a microlens array between an objective lens and a light detector. A sample is irradiated by the light sheet along a direction non-parallel to the sample plane. Light-field data may be acquired from the sample without needing to scan through the thickness of the sample. The microscope implements light-field acquisition in conjunction with selective plane illumination.

Abstract: A cartridge and cartridge system for use in an apparatus for analyzing a sample are provided. The system has a plurality of cartridges for different applications for a multimode instrument. The cartridges are removably engaged with a cartridge support in a “plug-in” format such that one cartridge may be removed from the apparatus and another cartridge may be easily installed. The cartridge support includes a plurality of cartridge positions that receive cartridges concurrently. One of the cartridges is a wavelength-tunable cartridge in which different light sources, excitation filters, and/or emission filters may be selected. Tuning is further accomplished by tilting the excitation or emission filters at desired angles relative to a beam of exciting light or emitted light.

Abstract: An optical system for exciting and measuring fluorescence of samples has a first laser; a deflection element; a mirror; and an optic fixed in relation to one another. A unit is linearly movable back and forth along the optical axis and is mechanically connected to an oscillating linear drive. The optic acts as a collimator and the mirror acts to deflect the collimated light diametrically opposite to the bundled light of the laser. A table for receiving sample holders for samples; an optical arrangement for imaging a second focal point; an aperture plate in the second focal point; a first spectral filter; and a first detector are parts of the optical system and a focusing beam of the light emitted by the laser and is deflected by the deflection element toward the mirror.

Abstract: A fluorimeter has a flash lamp, a measurement station with a receiver for microtitration plates, at least one measurement head disposed at the receiver and an evaluation station having a detector. Emission signals given off by a sample are evaluated by the detector. Light guides extend from the flash lamp to the measurement head from the measurement head to the detector. At the measurement station one measurement head is arranged above a sample and one measurement head beneath the sample. A change-over switch is formed by a pivotal bar which connects the light guides selectively to the upper or the lower measurement heads. On the pivotal bar are connections for the light guides which lead to the upper and the lower measurement heads. Connection of a respective measurement head can be brought selectively into correlation with the light source and the detector.

Abstract: A method and system for analyzing a solution for an agglutination pattern. The method comprises the steps of producing an illuminated image of the solution on an array of pixels, and assigning to each pixel in the illuminated image, a data value representing the intensity of the illuminated image on the pixel.

With the preferred processing procedure, the pixel array is separated into a plurality of zones, and the data values for the pixels in each zone are processed according to a respective predetermined procedure to determine values for a predefined set of variables. Then, those determined values are processed to determine whether an agglutination pattern is present in the solution, and if so, to classify that pattern into one of the predefined classes.
