The analytical ultracentrifuge (AUC) sample cell holds sample and reference buffer and during experiments and is exposed to high vacuum and rotor speeds up to 60,000 rpm. This video will demonstrate the rigorous attention to detail necessary for assembly, loading and alignment of this very important component of an AUC experiment.

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles. Deoxygenated blood from the body is received in the right...

A method of quantitating neutrophil adhesion is reported. This method creates a dynamic flow environment similar to that encountered in a blood vessel. It allows the investigation of neutrophil adhesion to either purified adhesion molecules (ligand) or endothelial cell substrate (HUVEC) in a context similar to the in vivo environment with sheer stress.

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes. Many viruses self-assemble into a fully functional unit using the infected host cell to...

A microfabricated device with sealable femtoliter-volume reaction chambers is described. This report includes a protocol for sealing cell-free protein synthesis reactants inside these chambers for the purpose of understanding the role of crowding and confinement in gene expression.
FAQs
Seals and fluid inlets or outlets work together to preserve a stable experimental environment. Effective sealing limits leaks, while controlled fluid movement supports reagent delivery and waste removal without disturbing the sample. In brain-slice and live-cell studies, this coordination helps maintain tissue conditions and reduces variation that could otherwise affect electrophysiological or imaging measurements.
Optical and electrode interfaces determine how researchers access neural samples for observation, recording, or stimulation. Their integration with the chamber allows measurements and manipulations to occur while the sample remains within controlled conditions. This is especially relevant when experiments combine live-cell imaging with electrophysiology, because the enclosure must support both visual access and electrical interaction.
Leak control, vibration limitation, and environmental stability are central factors in reliable chamber performance. A poorly assembled enclosure can alter fluid conditions, disturb recordings, or introduce changes unrelated to the neural sample. Careful construction therefore improves measurement consistency and helps distinguish biological responses from artifacts caused by mechanical or environmental instability.
A typical assembly brings together a chamber body, seals, fluid inlets and outlets, and interfaces for optical or electrode access. These components must function as a coordinated system rather than as isolated parts. Their arrangement determines whether researchers can maintain sample conditions while delivering reagents, removing waste, imaging cells, recording activity, or applying stimulation.
For brain-slice experiments, the chamber supports controlled conditions around the tissue while providing access for measurement and manipulation. Regulated perfusion can help deliver solutions and remove waste during the experiment. Optical interfaces support observation, whereas electrode interfaces enable electrophysiological recording or stimulation, allowing researchers to examine neural activity and cellular responses in prepared tissue.
A well-assembled chamber can support brain-slice preparation, electrophysiology, live-cell imaging, and stimulation experiments. By limiting leaks, vibration, and environmental changes, it promotes sample viability and more consistent measurements. These improvements strengthen reproducibility, helping researchers compare neural activity or cellular responses across experiments under controlled laboratory conditions.
