Hello all,

the antigen retrievel chart is still available from Biogenex. you just
need to call and request one.
They do not refer to the buffer as Hier but show the equivelant. For
example: citra=microwave heating in
antigen Retrievel Citra solution or equivelant. so it is still a very
useful chart. You will just have to cross
reference the pH used to the brand you have.

#800-421-4149, the chart is called Antigen Retrievel Reference.

Hope this helps.
