Visualization of cell-substratum adhesion plaques by antibody exclusion

Research output: Contribution to journalArticlepeer-review

We report on an antibody exclusion method for detecting cell adhesion plaques. Substrata coated by plasma fibronectin (pFN) appeared uniformly fluorescent when analyzed by indirect immunofluorescence using a specific anti-pFN antibody. When cells that had spread on the substrata were permeabilized and analyzed by indirect immunofluorescence, areas of non-fluorescence were apparent beneath the cells and in focal streaks along the cell margins. The nonfluorescent focal streaks were coincident with adhesion plaques visualized by interference reflection microscopy.
