Subject: Sirius Red F3B = Direct Red 28 = Congo Red???????

We are wanting to do the Picro sirius Red stain to demonstrate Collagen. I cannot find a supplier here in OZ/Australia ??

In trying to locate such, I have been told that Sirius red F3B with a C.I 35782 is also Direct Red 28 which is also Congo red - C.I add to our confusion. Need to order ASAP stain needed to make the Sirius Red Collagen stain (from J.A. Kiernan website)..please, can someone clarify this. Perhaps mwe cannot see the forest for the trees??  :)) Cheers & THANKS in advance,

Bruce in OZ.
