Plasma and Serum
The following comments about plasma apply equally well to serum.
It makes no real difference what the source of the plasma is, since it is the proteins that function as the adhesive, and these are very similar regardless of the animal involved. Lipemic samples should be avoided and preference given to clear, lipid free plasma.
Procedure
- Simply smear a tiny amount of the plasma over a clean, grease free microscope slide and pick up a section from the tissue flotation bath.
- Bake on as usual.
- After staining, the plasma should not be visible. If it is, then too much has been used.
