Image analysis and image processing as tools to measure initial rates of enzyme reactions in sections: distribution patterns of glutamate dehydrogenase activity in rat liver lobules.


To analyze regional differences in the activity of glutamate dehydrogenase in rat liver in situ, we developed an image recording and processing system for monitoring the formation of a colored final reaction product in time. All absorbance measurements of test and control reactions in time in consecutive sections were used to fit the data to a quadratic… (More)
