Hello,
        I am looking for any info on the shelf life of reagents in dry
form.
ie: Eosin y, Hematoxylin, Congo Red, etc.

        Will they last for more than 10-15 years and is there any way to
test
them for use.

        I just started in the lab here at AML in Louisiana and the
reagents
here date back to 85 and in most cases none are less than 8 yeas old.
                                                        thanx
                                                W.E.James Jr. H.T.
