Histological and Electron Microscope Staining for the Identification of Elastic Fiber Networks.

Abstract

Elastic fibers are a major component of the extracellular matrix and are present in many tissues. Routine histology and standard electron microscopy procedures often do not allow for clear identification of elastic fibers making their organization and ultrastructure difficult to study. In this paper, we describe staining methods and procedures to enhance the contrast of elastin at both the light and electron microscope levels.
