Blood Serum as an Adhesive for Paraffin Sections

Abstract

Diluted human and other mammalian blood serum (15 ml of fresh blood serum diluted with 10 ml of freshly distilled water, with 6 ml of 5% formalin solution in distiller water added) can be used as a good adhesive for paraffin sections. It is preferable to Mayer''s egg albumin-glycerol mixture because it is easily obtainable, can be quickly prepared, and sections are less subject to loosening after its use.
