I'm looking for a way to visualize a lysolecithin (LPC) lesion in the corpus collosum of a mouse. In published literature I saw the use of Monastral Blue #274011 by Sigma but this product has been discontinued.

Does anyone have experience with a similar product from another company?

Suggestions for a different substance with close enough features are welcomed as well (color that can be visualized by the naked eye and no effect on microglia or myelin at low enough concentrations).
