[Histonet] Monastral blue

[Hawkins, Hal K.]

We need to study changes in vascular permeability in animal models using
Monastral Blue B dye.  Apparently Sigma-Aldrich no longer supplies this
pigment.  Does anyone know of another source, or would anyone be willing
to share/sell us some?  Alternatively, is there another colloid that is
useful in the same way at the level of both light and electron
microscopy?
