Hi histonetters,

Currently I am doing IHC using human Ab on human tumor. I know it would
cause "messy" background. But this tumor was developed by injection human
tumor cell to nude mice. The results came out pretty good. I didn't use
conjugated primary Ab, but just traditional method. I think it's because
the tumor was developed in mice, the tissue would not contain endogenous
human serum that causes the "messy background", although the tumor is human
tumor. Am I right on this? Or my stain result just "fake"?
Hope I said it clearly. Could any expert give me help?

Thanks in advance!
