Table 8.10.   (from CD Chapter 8)
Proteinase activity in the pancreas of reptiles, birds and mammals
Enzyme activities expressed as the equivalent amount of bovine trypsin (casein or BAEE) or chymotrypsin (BTEE) under the same conditions. *A: 200-1,200 g RNase per gram pancreatic tissue; B: 20-100 g per gram pancreatic tissue; C: 0-20 µg RNase per gram pancreatic tissue. (from Vonk and Western 1984)
