Designed for researchers using IX3 open source concept IX83 and IX73 microscopes, cellFRAP deck system provides accurate and flexible live-cell photomanipulation as well as various evaluation options for data presentation. Diffraction-limited laser spot enables high-intensity and precise positioning of bleaching region across full FOV and negates need to move sample, while spot quality allows flexibility in position and shape of bleaching region and enables control of the bleaching area.
