Van Gieson Stain
Van Gieson stain is usually used for collagen fiber staining. Collagen fiber is distributed most widely and maximum among the three fibers.
A double staining based on the different affinities of acid fuchsin and Picric acid towards collagen fiber and muscle fiber. Collagen fiber will bind acid fuchsin and become red to pink, while muscle fiber will bind Picric acid and appear yellow.
