Description
Product Overview
The ProbeSeq Integrin β1 FRAPProbe™ System provides fluorescence-labeled probes for quantitative measurement of integrin-mediated cell–matrix interactions in live cells and engineered tissue models. The system enables analysis of receptor diffusion, focal adhesion formation, cell migration behavior, and extracellular matrix (ECM) binding dynamics.
This product supports mechanotransduction studies, cancer invasion research, biomaterials evaluation, and organ-on-chip models. Probe design ensures strong photostability, controlled photobleaching performance, and reliable fluorescence recovery for quantitative FRAP measurements.
The system is compatible with confocal microscopy, live-cell imaging platforms, microfluidic cell culture systems, and tissue engineering scaffolds.
FRAP Technology Advantages
FRAP provides real-time measurement of receptor mobility and cell adhesion dynamics within living systems. Unlike endpoint adhesion assays, FRAP enables direct quantification of receptor diffusion and focal adhesion remodeling under physiological conditions. This approach supports mechanistic studies of cell migration, tissue regeneration, and tumor invasion.
Molecular Detection Mechanism
Fluorescent Integrin β1 probes selectively bind integrin receptors localized at the cell membrane and focal adhesion sites. A defined region is photobleached using a focused laser pulse, followed by monitoring fluorescence recovery as unbleached receptors diffuse into the region.
Recovery kinetics provide quantitative measurements of receptor diffusion coefficients, mobile fraction, and adhesion dynamics. The system supports analysis of cell spreading, migration, and ECM interaction.
Target Design Strategy
Probe design targets extracellular Integrin β1 domains while preserving native receptor function.
