FW: background in FFPE spleen

From:"Philopena, Jennifer" <jennifer.philopena@canji.com>

Hi again.  Thank you all so much for your prompt suggestions.
I forgot to mention that my control antibody is clean.  Very clean.
Could this imply a "dirty" primary?
I'm going to call the company and ask about adsorption with mouse IgG's.
