Hi Peggy, No, this is a batch I have been using since 12/12. I purchased it from Sigma. It seems faint after the ammonium hydroxide . I did a run yesterday and I did get some blue, but faintly, not as bright as I am used to seeing. Everything else was picture perfect. Ray suggested that it may be a change in my tap water. I have our current report and am waiting on the report before that one. I am doing another run today and am considering rinsing in DH2O after the Alcian Blue and ammonium hydroxide. What do you think? Betsy

From where did you purchase it? I have a theory, but would like some more information first. Peggy A.

I have been running Movats for years and this is a new problem. I have checked lot #’s everything is the same. The solution is 1% pH 2.7. The slides are in solution for 20 mins, rinse for 5 mins in tap H2O, then in alkaline alcohol (90 ml 95% 10 ml ammonium hydroxide) for 1 hr then rinsed for 10 mins. But after hematoxylin the blue is either gone or very faint. Any suggestions?
