Congo Red Buffer is added to differentiate the stain. Congo Red Hematoxylin, a Mayer’s hematoxylin solution, is used to provide contrasting blue to purple nuclear staining. The β-pleated sheets of amyloid are suitable in size and shape to accommodate the Congo red molecules, which are held in the latticework of the β-pleated sheets.6 Birefringence is an intrinsic property of the amyloid fibril Congo red complex.7,8This kit is optimized for use on the BenchMark Special Stains instruments. The reagents are applied to tissue on microscope slides and mixed over the entire specimen. en
