アプリケーションノート （分析目的）- Applications for Reseach, Development and Process Analysis -
Topics
Correlation between fluorescence intensity and specific AFM force measurements on living Hela cells. A tip was functionalized with a toxin able to target any inositol-containing molecule. Fluorescent cells over-express GPI-anchored proteins and exhibit a high number of specific unbinding events (yellow retraction curve) whereas for most of the non-fluorescent cells, no event (red retraction curve), or a much lower number, can be detected.
Celgard® oriented Polypropylene membrane (TappingMode, Broadband-A Probe) is a good indicator of AFM force control. Tracking error would cause lateral forces to separate and damage the smaller strands.
Experimental data of force curves for a cantilever operated in PeakForce Tapping. The lever is driven by a sinusoidal wave and the curves are displayed as force versus time and force versus distance.
