Biochemical analysis of mouse serum Serum insulin levels were measured in a 96-well microplate using a commercial Morinaga Ultra Sensitive Mouse/Rat Insulin ELISA Kit (MIoBS, Japan)
However, this may reflect the existence of PDE as various isoenzymes (at least 11 members to this superfamily, each located in different sites within the cell, some of which are inaccessible to drugs)
