Figure 5From: Molecular mapping of periodontal tissues using infrared microspectroscopy Comparison of unstained periodontal tissue section with H and E staining and the associated IR mapping. The original periodontal tissue used for IR mapping (A), as defined by the adjacent tissue stained with H&E (B), correlates very well with the IR chemical map based on protein band intensity (C). The color bar indicates the relative intensity of the specific IR band in the tissue.Back to article page
