Are 10 week old samples in formalin still usable?

I have left my tumor samples in formalin for an extended period of time (around 10 weeks). Do you think I will be able to use them for TUNEL assay and get results? Thank you for your help in advance

Experiment: TUNEL assay cell type - PANC-1 human pancriatic cancer

Tissue that has been formalin fixed can last for a very long time. The only thing you should be careful at this point is antigen retrieval. I would recommend you to use Tris-EDTA pH 9 for that.
