Verhoeff's stain, also known as Verhoeff's elastic stain (VEG) or Verhoeff–Van Gieson stain (VVG), is a staining protocol used in histology, developed by American ophthalmic surgeon and pathologist Frederick Herman Verhoeff (1874–1968) in 1908. Introduction . differentiation with several changes of tap water and check Sodium thiosulfate is used to remove excess iodine and a counterstain (most often Van Gieson's stain) is used to contrast the principal stain. Prepare the working solution by adding in order the following as skin, aorta, etc. The Verhoeff stain is one of the most commonly-used stains to visualize elastic tissue, as found in blood vessel walls, elastic cartilage, lungs, skin, bladder, and some ligaments. on formalin-fixed, paraffin-embedded sections, A bacterial staining procedure using crystal violet and pink safranin counterstain that generally divides bacteria into either gram-positive or gram-negative and useful for considering associated pharmacology. Elastic Stain Kit ab150667 uses a modified Verhoeff's Van Gieson / EVG stain to stain elastic fibers / elastin in tissue sections in histology. The mucins are stained rose to red, nuclei are blue/black, and other tissue elements are yellow; B) Verhoeff’s elastic stain colors elastin fibers in skin black. made in larger quantities and stored in brown bottle in the dark at Deparafinize and hydrate to water. Figure 1. 1979 Aug;62(3):233-47.
