Thank you for the suggestion. Do you know very economical procedure for this? I buy commercial antibody, so there are very little and of course expensive-nothing to waste.

you could also directly label the primary antibody (biotin or Alexa-488)

no economical procedure. It's doubling the price of your antibody if not worse. That's why it would be better to buy it already labeled if possible.
I used reactive biotin from Pierce to label surface proteins (EZ-link sulfo NHs-LC biotin) that worked fine, and for fluorescent labeling, I used a kit from molecular probes to label monoclonal antibodies. But it is expensive (we were producing our own monoclonal antibodies, unless I would have bought them already labeled).
I don't remember exactly the price.

but If you already have the antibody, have a try with and without the primary antibody to see if you really have background. If you are working on tissues, I know there is a treatment to get rid of the Ig inside the tissue, but I don't know how.
