names (lissamine fast red as an example)
Is there another name for Lissamine Fast Red? I can't find it under this name in any dye catalog.
Five or six people identified at least three
different dyes in the answers to this HistoNet query in August
1998. This emphasizes the importance of identifying dyes by Colour Index numbers whenever possible. A name like "Lissamine" has no chemical significance and may be attached
to widely differing compounds! Some opinions follow
(mine is No. 3). Probably all are correct, and there
are different uses for the simlarly named dyes.

1. Another name for Lissamine Fast Red is Acid Red 37. You can try BDH with next Cat no 341772K and it comes in 25
2. I suspect that the dye you're looking for is Sulforhodamine B, also known as Lissamine rhodamine B 200, Acid rhodamine
B. The dyers assoc. refer to it as C.I.Acid Red 52. Its C.I.Number is C.I. 45100.
3. The nearest entry in Conn's Biological Stains (9th ed,, 1977) is amidonaphthol red 5B (C.I. 18055, Acid violet 7).
Synonyms include lissamine red 6B and many others. The Colour
Index number (or application name) is the most reliable
identifier of a dye. It should be mentioned in the published
instructions for a method. If it isn't, your best bet is to find
another, properly explained staining technique for the job.
4. My assumption has been that the lissamine fast red referred to is the same that Lendrum used in his published
method for muscle fibres. The dye name has the synonym Acid red
37, Colour Index no. 17045. It appears in Floyd Green's
excellent reference book "The Sigma Aldrich Handbook of Stains,
Dyes and Indicators" with the further synonyms anthranal red G
and fast light red B. The dye synonyms list I refer to most frequently as an easy-to-use first stop was published
as a "give away" by Difco in 1974.
