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.

Glass wool filters have been used to concentrate waterborne viruses by a number of research groups around the world. Here we show a simple approach for constructing glass wool filters and demonstrate the filters are also effective in concentrating waterborne viral, bacterial and protozoan pathogens.

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.

The Looking Glass Self

The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical self-perception,...
FAQs
Filtration performance reflects the interaction between the glass matrix and the way the sample moves through it. Interconnected pores determine how readily liquid or gas can pass and where particles may be retained, while pressure or vacuum provides the driving force. Changes in flow conditions can therefore influence particle capture and the consistency of clarification.
Two retention mechanisms operate within the porous medium. Surface screening holds particles at pore boundaries when they cannot pass through openings, whereas entrapment captures particles within the interconnected glass matrix as the sample travels through it. Together, these mechanisms reduce suspended particulate material without relying on a single capture location.
The composition of a sample affects how particles interact with the porous glass and how readily the sample moves through the cartridge. Buffers, cell lysates, and other laboratory solutions may contain different amounts or types of suspended material, so their filtration behavior can differ. This makes sample composition an important factor in achieving consistent clarification.
A basic workflow places the cartridge in the sample path, applies pressure or vacuum, and allows the liquid or gas to pass through the porous glass medium. Suspended particles are retained during passage, producing a clarified output. In biochemical preparation, this operation is performed before downstream analysis or purification when particulate reduction is needed.
Researchers can use these cartridges when buffers, cell lysates, or other laboratory solutions contain suspended particles that could enter a downstream system. Clarifying the sample before chromatography or analysis helps reduce particulate contamination and protects the associated equipment or analytical pathway. The resulting preparation can also support more consistent handling across experiments.
The main outcome is a reduction in suspended particulate material before a sample reaches a purification or analytical step. For biochemical solutions, this can improve sample handling by producing a cleaner input and limiting particulate contamination. Protecting chromatography or analytical systems in this way may contribute to more consistent experimental results.
