Biotinylated Cell-Penetrating Peptide Probe to Detect Protein-Protein Interactions
0 Views •
2025
This video demonstrates a technique that uses biotinylated cell-penetrating peptides to detect intracellular protein-protein interactions. The cell-penetrating peptides facilitate the conjugated peptide to enter a cell and specifically bind to its interacting proteins. The biotin, after binding to avidin, allows purification of the interacting proteins’ complex from a cell lysate.

Here we present a Ground Penetrating Radar (GPR) system based on a ground-coupled, densely populated antenna array for monitoring the dynamic process of subsurface water infiltration. A time-lapse radar image of the infiltration process allowed estimating the depth of the wetting front during the course of the infiltration process.

The goal of this protocol is to alter the penetrance of lethal skeletal mutant phenotypes in zebrafish by selective breeding. Lethal mutants cannot be grown to adulthood and bred themselves, therefore this protocol describes a method for tracking and selecting penetrance through multiple generations by progeny testing.
FAQs
Measured depth reflects the balance between applied force and the material’s resistance to entry. Hardness, stiffness, friction, and internal structure can each alter the depth response, so identical loading may produce different results in different materials. Considering these contributors helps engineers interpret penetration data as evidence about surface and subsurface behavior rather than as an isolated distance.
Probe geometry determines how force is transmitted into the tested material, while loading conditions control the driving input that produces the depth response. Changing either factor can reduce the comparability of measurements, even when samples are otherwise similar. Engineers therefore control these variables when assessing material properties, comparing specimens, or evaluating whether a result reflects the material rather than the test setup.
Probe penetration depth is useful because the response may reflect both the outer surface and material beneath it. This makes the measurement relevant to coating evaluation, layer-thickness assessment, and investigations of internal structure. Engineers should interpret the depth together with hardness, stiffness, friction, and loading conditions, because those factors influence the response and affect how confidently surface or subsurface behavior can be inferred.
Begin by selecting a probe geometry suited to the material and defining controlled loading conditions. Drive the probe into the sample, measure the resulting depth directly or relate the response to material behavior, and record the test conditions. Comparing results is most meaningful when geometry, force application, and measurement accuracy remain consistent across samples.
Applications include indentation testing, soil and geotechnical investigations, coating evaluation, and contact-based sensors. In these settings, the measurement can support assessments of strength, layer thickness, or structural condition. Its value extends from material selection and quality control to failure analysis, because the depth response provides a common way to examine how a material or structure responds to contact.
Use the data comparatively only after accounting for probe geometry, loading conditions, and measurement accuracy. A deeper or shallower response is not meaningful in isolation because hardness, stiffness, friction, and internal structure all contribute to resistance. Consistent testing allows engineers to support material selection, quality control, and failure analysis with results that are more reliable across samples.
