2025
This protocol describes a one-day method for the isolation of human fallopian tube epithelial cells. Isolated epithelial cells can be plated in 2-dimensional (2D) culture or dissociated into single-cell suspensions and utilized in downstream experiments, including flow cytometry and single-cell RNA sequencing.

Chip-in-a-Tube-Based Digital PCR for Quantification of Single Nucleotide Variants

2025
This video demonstrates the utility of digital PCR in a chip-in-a-tube format for the detection of single nucleotide variations in DNA samples. A single PCR reaction is partitioned into chambers that act as independent PCR reactions, and the detection of fluorescence signals from the amplified targets in the chambers is used to compute the frequency of the variant allele in the sample.

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Tube thoracostomy (chest tube placement) is a procedure during which a hollow tube is inserted into the thoracic cavity for drainage of fluid or air. Emergency chest tube insertion is performed for definitive treatment of tension pneumothorax, traumatic hemothorax, large-volume pleural effusions, and empyemas. Irrespective of the cause of air and fluid accumulation in the pleural space, the...

Tissue-engineered implants for reconstructive surgery rarely progress beyond preclinical trials due to laborious ex vivo culturing, which includes complex and expensive scaffold components. Here, we present a single-staged procedure designed for urinary diversion with an accessible collagen-based tubular scaffold containing autologous micrografts.

A Modified Roller Tube Method for the Long-Term Culture of Rodent Brain Slices

2025
This video demonstrates a modified roller tube method for the long-term culturing of brain slices from a rodent model. First, the brain slices are attached to coverslips. Then, flat-sided roller tubes with a hole on the flat side are taken, and the coverslips are positioned on the hole using adhesive discs. Finally, a nutrient medium and a carbon dioxide and air mixture are added to the tube, and the tubes are incubated with a rolling motion.
FAQs
Reagent sequencing coordinates preparation, reaction, and detection so that each stage occurs under conditions compatible with the next. Adding components in a planned order helps prevent premature reactions or interference between stages. This organization is important when several assay processes share one vessel, because the sequence directly affects whether the workflow remains consistent and produces interpretable results.
Keeping the sample in one vessel removes transfer steps that could leave material behind or introduce contaminants from handling. The benefit is especially relevant when the available sample is small or when multiple manipulations would otherwise be required. Fewer container changes also simplify the workflow, making handling more consistent across repeated biology experiments.
Compatibility among the assay stages is the central consideration. Preparation, reaction, and detection must function within conditions that can be established through the planned reagent sequence. The approach is most practical when rapid processing, limited sample volume, or reduced handling is important. If the stages require incompatible conditions, combining them in one vessel may not be suitable.
A typical workflow begins by placing the sample in one reaction vessel, then adding the required reagents in a planned sequence. The combined preparation, reaction, and detection stages proceed under compatible conditions, followed by observation or measurement of the assay outcome. This sequence should be organized before starting so each addition supports the next stage without unnecessary transfers.
Researchers may choose this approach when an assay must process samples rapidly, conserve limited material, or reduce handling complexity. It is also useful when transferring samples between containers would create avoidable loss or contamination concerns. By consolidating stages, the method can streamline molecular analysis and support a more efficient, consistent experimental workflow.
For molecular analysis, combining assay stages can reduce material use and shorten the handling pathway from preparation to detection. The resulting workflow may improve efficiency and consistency because fewer transfers are required and the reagent sequence is planned in advance. These features make the approach relevant when laboratories need streamlined processing without repeatedly moving a sample between vessels.
