said substrate in said non-human model
- Fractionating said extract on an affinity resin column,
wherein the affinity resin of the column comprises a protein
bound to solid support, & wherein said protein is selected
from: anhydrotrypsin, inactive carboxypeptidase E having
a point mutation in the AA seq of the carboxypeptidase E
of Glu-342 to Gln-342, & carboxypeptidase E used in the
