FIG. 2.

Characterization of extracellular matrix (ECM) microarray. (A) Specified position and immunofluorescent image of an ECM microarray probed with a primary antibody against collagen I and using a secondary antibody conjugated to Alexafluor 633. Immunofluorescent image was obtained using a GenePix 4200A scanner. (B) Correlation of fluorescence intensity and rat collagen I concentration after protein printing (□) and following incubation (▪) for 24 h at 37°C in cell culture medium.
