[Histonet] buckground nuclear stain in Immunohistochemistry

[Hernan Aldana]

Dear all

I made immunohistochemistry for androgen receptor in testicular tissue
with Hydrochloric Acid Epitope Retrieval Method. I have a background
stain remarkably in chromosomes in spermatocytes. Some advises to stop
this reaction?
Thanks
