Assessment of the Murine Tumor Microenvironment by Multiplex Immunofluorescence

We describe the staining methods used for simultaneous detection of tumor microenvironment components as well as the automated quantification methodologies. This method uses mouse formalin-fixed paraffin-embedded tissues and multiplex immunofluorescence (Multiplex IF) followed by multispectral imaging. Currently, this methodology has shown to have a valuable role in murine immunoprofiling, and can be useful when evaluating the changes incurred on the tumor microenvironment upon various immunopreventive strategies.
