Tracking protein conformation in live cells
SpletIntroduction. As nanotechnology is taking an increasing attention in fabrication of nanomaterial-based compounds for protein 1 and cell delivery agents, 2 revealing the impact of the physicochemical properties of nanoparticles (NPs) such as their chemical composition on the protein structures and cells viability has become critically necessary. … SpletCell-penetrating peptides (CPPs) are short peptides (fewer than 30 amino acids) that have been predominate used in basic and preclinical research during the last 30 years. From they are not only ability by translocating themselves within cell but also facilitate drug instead CPP/cargo complexities to translocate via and plasma membrane, they have potential …

SpletIsolated PBMCs (1x10 6 cells/well) from uninfected control chickens were seeded into a 96-well cell culture plate and incubated at 39°C, 5% CO 2 for 12 hrs to identify flagellin dependent CS NPs cell uptake. Attached cells were treated with either medium or 10 μg F-protein or same concentration of F-protein coated CS NPs (CS NPs-F) for 4 h. SpletI have a broad interest in developing biointerfacial and biosensing sciences-based strategies to solve biomedical problems involving molecular recognition and cellular signaling. Employing these strategies, I’ve made significant contributions in the field of cell adhesion and mechanical signaling (Proc Natl Acad Sci U S A, 2015; Biophys J, 2016; …
Splet13. dec. 2024 · However, these interactions are poorly investigated, mainly due to the methodological limitations. Here, we have developed a co-immunoimmobilization assay called Co-II that enables the direct visualization of protein–protein interactions in the membrane of living cells at the single-molecule level. Co-II is based on the intuitive … SpletRecently, super-resolution microscopy and single-particle tracking methods have been developed to follow individual protein complexes in live cells. Here, we described how this technology can be adapted to visualize the DNA scanning process of Cascade assemblies in Escherichia coli cells.
Splet21. okt. 2024 · FRET (Förster resonant energy transfer), relying upon exotic quantum effects, fixes pairs of such beacons in target proteins so that their light changes as the protein’s conformation changes. This enables a certain amount of research on protein dynamics as they shape-shift inside cells. SpletEukaryotic transcription factors (TF) function by commitment up short 6-10 bp DNA recognition sites located near theirs target genes, any are interspersed through vast genomes. Suchlike process surmounts ton specificity, effi and celerity our using a moln mechanism which remains poorly insight. Combining biophysical experiments, theory …
