Re: [Histonet] NaCl in antibody diluent

From:"Anthony Reilly"


NaCl is a normal component of PBS.  The high salt buffer DAKO are most
likely referring to is TBS which is a Tris buffer with 0.9% NaCl added. 
As others have stated this is used to reduce background.  In my
experience this will only give minimal improvement.  If you are
suffering background you are best to investigate your dilution, blocking
if any and the type of detection system used.

Has anyone tried NaCl in there diluent buffer for IHC, if so what
concentration. I read about it in DAKO's immunostaining methods
but they don't state the concentration. This is my last chance with my
background problem. I have a sticky collagen issue I cant get rid of.
