Comparison of methods for assay of fecal proteolytic activity.


Fecal proteolytic activity (FPA) in ten normal dogs was readily detected either calorimetrically using azocasein substrate or by radial enzyme diffusion into agar gels containing casein substrate. Daily FPA ranged from 17 to 207 azocasein units/g (ACUIG) or 4 to 18 mm of casein hydrolysis, while mean 3-day FPA ranged from 58 to 10 1 ACUIG or 7 to 15 mm… (More)
