Fig. 3. Western blot analysis of mucus CA from guinea pig. For each analysis
identical amounts of CA activity applied with the samples were: guinea pig
colonic mucus with 0.87 U ml-1 CA activity, isolated mucus CA with
5.3x10-3 U ml-1 CA activity. *Guinea
pig CAI was applied at an amount of 0.87 U ml-1 CA activity as a
positive control for guinea pig mucus. Applying CA I at
5.8x10-3 U ml-1 as a control for isolated a mucus
CA did not result in a visible band (not shown).
