Does the line express FcR's ? If so, you could block with mAB against FcR.

Subject: Fc Blocking - Mutz-3

I am currently working with the DC-like precursor cell line, Mutz-3. I am having some
trouble with non-specific binding of my isotype control antibodies. I am using FITC
(IgG2a), PE (IgG1) and PECY5 (IgG1) - conjugated antibodies. 

I do block the cells with FCS, but was wondering whether anyone has encountered this
problem with, or has any specific blocking protocols when using Mutz-3. Any advice would
be greatly appreciated.
