I am assuming that you have already worked-up your antibodies on GMA embedded tissue......
If you have then you should be OK for months depending entirely on the epitope in question.
If you have not then you could be in for an unpleasant surprise as many antibodies  are not able to penetrate the polymerized GMA which cannot be etched.

Assuming that  GMA blocks are stored under optimum conditions,i.e. with desiccant  and at -20C; how long can they be stored and still obtain meaningful immunohistochemical staining?.
