I would look at the antibody dilution and redo your titer study, your primary antibody is probably too concentrated.

Subject: [Histonet] Factor XIIIa background staining problems

We have been experiencing Factor XIIIa background staining problems and
cannot seem to find an answer to fix it. We use Cell Marque's Factor XIIIa
clone EP3372 at a dilution of 1:250. We have tried many different protocols
(i.e. enzyme pretreatment, high and low pH pretreatment, different
incubation times, etc.)and nothing seems to fix this background staining.
Our vendor told us that the dilution is good but we are questioning the
actual dilution or the shelf life of the antibody. The antibody is a long
ways from reaching the expiration date but we are still questioning it's
stability. Has anybody else experienced this or know a solution?
