Description
Product Overview
The ProbeSeq E-cadherin FRAPProbe™ System provides fluorescence-labeled probes for quantitative measurement of E-cadherin dynamics in live cells and engineered tissue models. The system enables characterization of cell–cell adhesion strength, junction remodeling, receptor diffusion, and epithelial barrier integrity.
This product supports epithelial transport studies, cancer metastasis research, tissue engineering models, and organ-on-chip barrier validation. Probe design ensures high photostability, controlled photobleaching behavior, and reproducible fluorescence recovery for accurate FRAP measurements.
The system is compatible with confocal microscopy, live-cell imaging platforms, microfluidic cell culture systems, and gut- and lung-on-chip models.
FRAP Technology Advantages
FRAP provides real-time measurement of protein mobility and cell junction stability within living systems. Unlike endpoint assays, FRAP enables direct quantification of adhesion molecule diffusion, junction assembly, and barrier remodeling under physiological conditions. This approach is particularly valuable for studying epithelial integrity, tumor cell invasion, and tissue barrier function.
Molecular Detection Mechanism
Fluorescent E-cadherin probes bind specifically to extracellular domains of E-cadherin at cell–cell junctions. A defined region is photobleached using a focused laser pulse, followed by monitoring fluorescence recovery as unbleached molecules diffuse into the bleached area.
Recovery kinetics provide quantitative measurements of diffusion coefficients, mobile fraction, and junction stability. The system supports analysis of adhesion remodeling, epithelial barrier disruption, and signaling-induced junction changes.
Target Design Strategy
Probe design targets extracellular E-cadherin domains while preserving native adhesion function.
