2025
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.

Predator-Prey Interactions

2026
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...

A technique for laboratory estimation of net trophic transfer efficiency of polychlorinated biphenyl (PCB) congeners to piscivorous fish from their prey is presented. To maximize applicability of the laboratory results to the field, the piscivorous fish should be fed prey fish that are typically eaten in the field.
FAQs
Separating these domains makes reporter activation conditional on protein association. The bait carries the DNA-binding domain, while the Prey Protein carries the transcriptional activation domain. When the two proteins interact, their attached domains are brought together, connecting a molecular contact to measurable reporter expression instead of requiring direct observation of the proteins themselves.
Reporter expression indicates that the tested prey and bait may associate under the assay conditions. It should therefore be regarded as evidence for a potential physical interaction rather than definitive confirmation. The result is especially useful for generating a molecular hypothesis that can later be examined through interaction-validation approaches.
Testing multiple candidate Prey Proteins with a known bait can identify possible interaction partners associated with that protein. Comparing which candidates produce reporter expression helps researchers develop a broader picture of protein relationships, organize potential connections within cellular pathways, and propose functions for proteins whose roles remain uncertain.
The workflow centers on preparing a genetic fusion that links the candidate Prey Protein to a transcriptional activation domain, pairing it with a bait linked to a DNA-binding domain, and assessing reporter expression. A reporter signal then provides the assay readout used to judge whether the candidate may associate with the known bait.
Researchers use this approach when they want to discover candidate interaction partners, investigate how proteins connect within cellular pathways, or gain clues about protein function. Because the assay can associate a candidate protein with a known bait through reporter output, it supports exploratory studies that produce focused hypotheses for subsequent investigation.
Within biological techniques, prey-based interaction testing provides a way to translate protein association into a reporter-based experimental outcome. The resulting evidence can contribute to interaction maps, pathway analysis, and functional studies. Its main value is hypothesis generation: reporter results identify relationships that researchers can further evaluate as possible molecular interactions.
