Notes:
The effects of epoxy resin formulation on tissue contrast and organelle size were evaluated by examining thin sections of rat liver in the electron microscope and by doing a simple morphometric analysis of peroxisome and nuclear size. Contrast was greatest for tissues embedded in the Quetol formulation of Kushida and least for tissues embedded in the Ladd formulation. Epon 812, Epon-Araldite, and Spurr formulations gave results intermediate to those of the Quetol and Ladd formulations. Organelle size was greatest for tissues embedded in the Ladd formulation and smallest for tissues embedded in the Spurr formulation. The maximum size differences were approximately 15%. Epon 812, Epon-Araldite, and Quetol formulations gave results (for organelle size) intermediate to those of the Ladd and Spurr formulations. The gross shrinkage properties of the epoxy resin blocks were all the same and, therefore, could not account for the differences in organelle size.
