Akemi = According to the Biological Stain Commission, dye often get better 
with age.  If you can run a control slide with a stain that uses the dye and 
it is positive, GLP regs allow you to put an expiration date 1 year from 
that time on the dye.  You can keep doing this procedure and redate the dye 
for a long time.  Chemicals, on the other hand, can outdate.  Your best bet 
is to dispose of them properly.
