A Microfluidic Cartridge-Based Detection System for Allergen-Specific Immunoglobulin E

2025
This video demonstrates a protocol for detecting serum-specific immunoglobulin E using a microfluidic cartridge-based chemiluminescence system. Serum IgEs interact with distinct allergens immobilized in the reaction zone of the cartridge, which are subsequently detected with peroxidase-conjugated anti-IgE antibodies and a chemiluminescent substrate, allowing simultaneous detection of multiple allergen-specific IgEs.

We describe a protocol for filtration of water samples with a filter cartridge and extraction of environmental DNA (eDNA) without having to cut open the housing to remove the filter. This protocol is developed for metabarcoding eDNA from fishes, but is also applicable to eDNA from other organisms.

We have developed an effective methodology for sampling and analysis of odor signals in order to understand how they may be used in animal communication. Particularly, we use headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry to analyze the volatile components of animal odors and scent-markings.

In a piloting scent tracking task, the ability of the rats to return to a refuge with food using visual an odor trail or using dead reckoning in infrared light, the integrated record of previous movements, demonstrates that the hippocampus is necessary for dead reckoning.
FAQs
Odorant molecules first bind to receptors in the nasal olfactory epithelium, where they activate neural signals. Those signals then travel through the olfactory bulb before reaching higher brain regions. This pathway gives researchers a way to connect a controlled chemical stimulus with activity at successive stages of olfactory processing.
Controlled release helps keep the amount of volatile compound presented more consistent across trials. That consistency reduces differences caused by uneven odor delivery, making neural or behavioral responses easier to compare. It is especially important when researchers examine changes across subjects, repeated presentations, or different experimental conditions.
A consistent odor presentation provides a defined sensory input against which neural responses can be examined. Researchers can then investigate how the brain detects and represents that smell as signals move through the olfactory bulb to higher regions. This supports analysis of olfactory processing rather than responses confounded by changing stimulus delivery.
The cartridge is used to present an odorant through an inhaled air stream, allowing the experimenter to provide a controlled olfactory stimulus. Responses can then be compared across trials, subjects, or conditions. The standardized presentation supports reproducible experiments in which differences in perception, neural activity, or behavior can be interpreted more consistently.
Scented cartridges can support studies of sensory perception, neural coding, learning, memory, and odor-guided behavior. Their value differs by research question: perception studies address how smells are detected, coding studies examine representation, and learning or memory studies relate odor exposure to experience. Behavioral experiments can assess responses directed by odors.
By presenting odorants more consistently, researchers can compare responses between experimental conditions without relying on substantially different stimulus amounts. Depending on the study, the measured outcome may relate to sensory perception, neural activity along olfactory pathways, learned associations, memory, or behavior guided by the odor. The approach therefore links stimulus control with interpretable comparisons.
