Congo corinth G is one of the dyes in Geschickter's solution, with Azure A. This solution is used to stain frozen sections for rapid diagnosis. The sections look very similar to those stained by polychromed methylene blue. Its structure is very similar to Congo red, and has been used to demonstrate amuloid.
