HBQ Stain
Hello Histonetters:
My pathologist returned from a meeting with a request for an HBQ stain
(Hall's and Brunt's Quadruple stain). One of the components is Direct Red
(C.I. 28160). I have done a little research and have discovered that Congo
Red is also called Direct Red Y, R and C, but the C.I. # is different. Sigma
only lists Congo Red in their catalogue and I couldn't locate Direct Red in
any of my other usual sources. Can anyone recommend another distributor that
I might try? Also, since the procedure calls for a 0.5% aqueous Direct Red
solution (appears to be a counterstain), what are the chances that
substituting Congo Red will work?
Any input will be greatly appreciated!
Thanks,
Diane
