Biological Activity for Congo Red
Congo Red is a VGlut inhibitor; decreases synaptic transmission in the dentate gyrus. Also an amyloid fibril-binding dye; inhibits Fib-beta A neurotoxicity by inhibiting fibril formation or by binding to preformed fibrils. Also inhibits the pancreatic islet cell toxicity of diabetes-associated amylin. Excitation wavelength is 497 nm.
