Dye binding occurs mainly via Van der Waals forces and hydrogen bonds. Verhoeff’s elastic stain binds to elastic fibers withhigher affinity than compared to other cell structures. The Ferric Chloride Oxidizer oxidizes the Hematoxylin to hematein. Hematein is a compound that has high affinity for iron together with the second mordant, Lugol’s Iodine, to form an iron hematein complex and chelates with the elastic fibers in the tissue. The Differentiator uses lower strength ferric chloride. This step is used to differentiate the target stain from non-specific binding. The rinsing of the Differentiator removes the loosely bound stain from cell structures other than elastic fibers.The Special Stains Van Gieson CS stains red blood cells and muscle yellow and collagen pink to provide contrast with the dark purple to black elastic fibers.This kit is optimized for use on BenchMark Special Stains instruments. The reagents are applied to tissue on microscope slides and mixed over the entire specimen. en
