To all of you who use Alcian yellow:
Alcian yellow is no longer made, and probably will not be made again
because the starting material for its synthesis is not available
either. We have been working hard to find an alternative that is
indistinguishable from Alcian yellow, and are please to report that
we have some promising leads. We need another 6 months or so to
conduct shelf-life studies. In the meantime, you can conserve your
dye (if you make up your own solutions) by using only 0.2% instead of
the usually prescribed 1.0 %. The dye simply is not very soluble in
water, and a 0.2% solution (0.2 g per 100 ml) actually has about as
much dissolved dye as one made with 1.0 g per 100 ml.
If you would like to be contacted as more information becomes
available, please send me an email.
