Vector has an avidin-biotin blocking kit that works well by itself or mixed with reagents- very reasonable cost.

Subject: [Histonet] Has anyone used a biotin block in their antibody diluent?
Has anyone ever used a Biotin block in their primary anitbody diluent? I have been having problems with nonspecific staining, which I suspect is due to endogenous biotin. I plan on decreasing my antigen retrieval time, as someone has told me that an antigen retrieval that is too vigorous may cause the unmasking of biotin, and its subsequent staining. I would like to know if anyone has had any luck using a biotin block in their diluent because I may try that as well.
