Fig 2. Effect of gel modifications on cell viability as determined by MTT assays. Remaining percentage of viable cells in modified cell carrier devices relative to control cell carrier devices (control) with result for each condition reported (average of triplicate experiments). Error bars indicate the SD for each triplicate series. Cell carrier devices are modified by exposure to the following: glut 0.3% (0.3% glutaraldehyde for 2 minutes); glut 1% (1% glutaraldehyde for 10 seconds); and ASC (ascorbate coculture) (printed with permission from the Mayfield Clinic).
