AW: [Histonet] Chemicals that inactivate the primary antibody

[Rene J Buesa]

I am completely confused.
IF you have an epitope in the tissue and you react with it an specific antibody "that is it". The epitope will have reacted and I do not see any way in which you can add another antibody to that initial epitope. From the reactive point of view, the epitope is "blocked" to react with another, unless the reaction is not totally specific and "there is room for another".
I just cannot imagine a way of doing this.

Hi TF and all interested,

I think I know what you want, but unfortunately I don't know how to answer 
your question (it is something I'd like answered myself!!)  To re-word for 
the sake of all interested:

You want to perform double-immunofluorescent staining using 2 primaries 
that were raised in the same species.

An additional question for clarification is: Do you want to do this on 
paraffin or frozen sections?

Maybe someone can help figure it out...

Merced
