This video describes an ELISA-based technique that detects protein-protein interactions between two proteins by measuring the binding of the second protein to the immobilized first protein. The bound second protein is detected using specific antibodies labeled with an enzyme, such as horseradish peroxidase.

Phage display is a powerful technique to capture proteins or protein moieties that interact with an immobilized molecule of interest. Once a decision of the type of phage cDNA library to create and screen has been made, the protocol described here permits efficient affinity selection leading to identification of interactors.

This video demonstrates the procedure for in vivo imaging of C. elegans expressing prion-like proteins tagged with red fluorescent protein. The protocol involves immobilizing nematodes on an agarose pad for time-lapse confocal microscopy, revealing protein aggregation and transport within and between cells. This technique is crucial for studying protein aggregation related to neurodegenerative diseases.

2025
This video demonstrates the generation of neural progenitor cells from non-transgenic and transgenic human pluripotent stem cells (hPSCs). hPSCs are differentiated into neural progenitor cells using a neuronal differentiation medium. While differentiation is induced in non-transgenic cells using small molecules, the transgenic hPSCs are differentiated by adding an antibiotic that induces the promoter for a neuronal differentiation-specific transcription factor.

An In Vivo Assay to Detect Mitophagy in Transgenic Nematodes
0 Views •
2025
This video demonstrates an in vivo assay to study mitophagy in Caenorhabditis elegans. Upon exposing the nematodes to a mitophagy-inducing drug, the occurrence of mitophagy is assessed by co-localization between DCT-1, a mitophagy receptor on the damaged mitochondria, and the autophagosomal membrane protein LGG-1.
FAQs
An affinity tag provides a handle for recovering the expressed bait protein together with molecules bound to it. After expression in a living cell or organism, researchers can use the tag during purification or a pull-down assay to isolate the bait-associated material. Detecting the recovered partners then supports analysis of protein interactions and molecular complexes.
A reporter can indicate where or when the engineered bait is expressed or can provide a signal linked to an interaction-based screening strategy. This adds a detection route beyond direct purification. By connecting bait expression or binding events to an observable signal, researchers can identify interaction-related behavior within a cellular context.
Expression in a living cell or organism allows the bait protein to encounter molecules within a cellular environment rather than only in an isolated mixture. This context can help researchers examine protein function, molecular complexes, and signaling pathways as they occur in biological systems. The resulting interaction information contributes to broader protein-network analysis.
The workflow begins by introducing a gene encoding the bait into a living cell or organism. Researchers then express the engineered protein, often with an affinity tag or reporter, and allow it to bind potential partners. Purification, pull-down assays, or interaction-based screening can subsequently recover or detect associated molecules for further study.
Such experiments can reveal molecules that associate with the bait and help characterize the composition of molecular complexes. The findings may also support mapping of signaling pathways and analysis of protein networks. Interpreting these interaction patterns alongside the bait’s studied function can clarify how proteins participate in cellular processes.
The strategy is useful when researchers need to investigate protein function, regulation, or interactions in a cellular setting. It can contribute to studies of disease mechanisms by identifying relevant molecular associations and pathways. The same information may help highlight therapeutic targets, particularly when altered protein networks or signaling relationships are under investigation.
