A gel tray for a bacterial transformation lab exercise has a plastic body with four parallel gel channels and four filling ports, one for each channel into which unmodified bacteria and heat-shocked bacteria can be injected by students along with appropriate reaction constituents to demonstrate transformation of the bacteria under visualization. A seal may be provided to seal the tops of the gel channels and a lid can cover the gel tray during incubation.

A monitoring system for monitoring a process includes a housing with a viewing panel. The viewing panel includes a view port. An emitter generates light and illuminates an observation zone of the process. A detector is disposed within the housing and is configured to detect light entering the housing through the view port and create a plurality of images of the process in the observation zone. A thermal regulation system is configured to generate heat in the vicinity of the viewing panel of the housing so as to increase the temperature of at least the view port above ambient temperature.

The present invention concerns the field of high-efficiency, quality-controlled production of blue-green algae for direct human consumption, for extraction of proteins, vitamins, and amino acids, and for production of organic materials loaded with the special isotope 13C.

It is an object of the present invention to describe a high-efficiency photobioreactor.

Embodiments of the present disclosure describe bioreactor systems that integrate phototrophic organism cultivation with energy harvesting, methods of using said bioreactor systems, and the like. The bioreactor systems can comprise a bioreactor, wherein the bioreactor is configured to cultivate a phototrophic organism in a liquid growth medium, and at least one transparent photovoltaic panel positioned between the bioreactor and a light source, where the transparent photovoltaic panel transmits select wavelengths of light and absorbs select wavelengths of light.

Zebrafish are a powerful model for investigating cardiac repair due to their unique regenerative abilities, scalability, and compatibility with many genetic tools. However, characterizing the regeneration process in live adult zebrafish hearts has proved challenging because adult fish are opaque and explanted hearts in conventional culture conditions experience rapid declines in morphology and physiology. To overcome these limitations, we fabricated a fluidic device for culturing explanted adult zebrafish hearts with constant media perfusion that is also compatible with live imaging. Unlike hearts cultured in dishes for one week, the morphology and calcium activity of hearts cultured in the device for one week were largely similar to freshly explanted hearts. We also cultured injured hearts in the device and used live imaging techniques to continuously record the revascularization process over several days, demonstrating how our device enables unprecedented visual access to the multi-day process of adult zebrafish heart regeneration.

An incubator configured to receive a predetermined number of cell culture chamber devices, each cell culture chamber device including an enclosure configured to contain a cell culture media. The incubator has a housing including an incubation chamber configured to contain at least a respective part of the cell culture chamber devices when received by the incubator, and at least one registration and/or detection device being integrated with the incubator and being configured to register and/or detect an illumination or visualisation signal after passing, reflecting, or propagating through at least a part of the enclosure of at least one of the predetermined number of cell culture chamber devices when received by the incubator.

A method for evaluating an adherent cell includes: obtaining an image of an adherent cell accommodated within a culture container; and determining whether the adherent cell is adhering to the culture container based on at least a profile shape of a contact portion of the adherent cell that is in contact with the culture container, the profile shape being specified from the image.

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.

A bioreactor includes a culture medium vessel housing culture medium. The culture medium vessel further includes a first side surface including a first transparent optical window; and a second side surface parallel to the first surface and including one or more sensor adapters to fix optical sensors. A cell retention vessel is disposed underneath and connected to the culture medium vessel, the cell retention vessel housing biological cells and having: a top surface that intersects a base of the culture medium vessel, and a second transparent optical window indented into the top surface at a first corner of the top surface. A semipermeable membrane is disposed at a bottom of the cell retention vessel, and a frame comprising a grid is disposed underneath the semipermeable membrane.
