   1. Two pieces about 1 mm in length taken from each end of the glomeruli containing core are placed in 3% glutaraldehyde for electron microscopy.
   2. A segment of glomeruli containing core measuring 3-6 mm in length is placed in Michel's solution for immunofluorescent microscopy.
   3. A segment of glomeruli containing core measuring 8-10 mm in length is placed in formalin for light microscopy.
   4. Any additional cores should be placed in formalin.
