FIG. 3. — Viability of cultured cells on extracellular matrix (ECM) protein arrays. (A) Live/dead staining reveals viability of HepG2 cells on ECM combinatorial array. Co-localization of green (live) and red (dead) fluorescence results in a yellow signal. (B) Brightfield image (20×) of a single HepG2 island after exposure to Trypan blue. Brightfield images were obtained using an Olympus digital camera mounted on a Nikon TS100 microscope. Fluorescent images were obtained using a GenePix 4200A scanner.
