Immunohistochemistry (IHC) combines immunological and enzymatic techniques to localize and evaluate antigen expression in tissue sections. Single-stain immunohistochemistry may be evaluated by pathologist light microscopic review or image analysis. Mosaic’s IHC assays are focused on immuno-oncology, immunology, signal-transduction pathways and relevant targets for cancer therapy. Mosaic has experience testing over a thousand antibodies for IHC and is validating numerous new assays on a rolling basis. Please contact us if the assay of interest is not on our list.
