A device was created to demonstrate electromyography-based control to a lay audience. After the success of the initial device, a second device was made with greater flexibility in functionality for demonstration and research purposes. This protocol describes the process of building and calibrating both devices.

Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings. Articulating Projections Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Calcium-Dependent Hydrophobic Interaction Chromatography: A Technique to Purify Calcium-Binding Proteins Based on Hydrophobic Interactions

2025
In this video, we demonstrate the purification of calcium-binding protein from a dialyzed cell lysate through calcium-dependent hydrophobic interaction chromatography. The calcium-binding proteins expose a hydrophobic region upon binding with calcium, facilitating interaction with a hydrophobic group on resin. Later these proteins are eluted using calcium chelator EDTA that reverses the interaction.

Proteins are often used to mark arthropods for dispersal research. Methods for administering internal and external protein marks on arthropods are demonstrated. Protein mark detection techniques, either through indirect or sandwich enzyme-linked immunosorbent assays (ELISAs), are also illustrated.
FAQs
The key event is lateral movement within the lipid bilayer. Once lipophilic fluorescent molecules enter a membrane, they can spread along connected membrane surfaces, allowing the signal to follow neuronal projections such as axons and dendrites. This membrane-associated route preserves the anatomical path of the labeled structure rather than depending on movement through the surrounding aqueous extracellular space.
Their water-repelling character favors association with lipid-rich membranes instead of dispersal through aqueous extracellular spaces. This allows the label to remain connected to membrane surfaces and produce durable visualization of cellular extensions. In neural tissue, that property is especially valuable when researchers need to examine long projections while retaining their relationships to surrounding anatomical structures.
Hydrophobic marking contributes anatomical information that complements the molecular and functional information provided by other approaches. Genetic and immunohistochemical methods can identify cellular or molecular features, while electrophysiology addresses neural activity. Membrane-based fluorescence adds a way to visualize neuronal projections and their spatial organization, helping researchers relate circuit structure to other experimental measurements.
Durable labeling helps maintain visible anatomical relationships during microscopy-based examination of complex specimens. Rather than providing only a transient indication of a cell or projection, the persistent membrane-associated signal can support tracing across connected structures. This makes it easier to interpret how axons, dendrites, and other labeled elements are arranged within neural tissue.
A general workflow introduces a lipophilic fluorescent dye to the biological specimen, allowing the molecules to insert into lipid bilayers and spread across connected membrane surfaces. Researchers then examine the fluorescent labeling by microscopy and follow the labeled neuronal structures. The resulting observations can be organized into an anatomical representation of projections and tissue relationships.
Researchers can use the technique when they need to trace axons or dendrites and map relationships among neuronal structures. Its value is greatest in microscopy-based circuit analysis, where preserving the path and organization of membrane-connected projections supports anatomical interpretation. The method therefore helps investigate how neural elements are arranged within complex specimens.
Labeling provides a way to examine neuronal projections while retaining their anatomical context, which is relevant when neural structure changes over time. In developmental studies, it can support visualization of projection organization, while injury-focused work can use the same anatomical perspective to examine altered structures. These observations can be combined with complementary molecular or functional methods.
