Additional file 3: of Physical basis of the ‘magnification rule’ for standardized Immunohistochemical scoring of HER2 in breast and gastric cancer

Abstract

Figure S3. Scatter-plot of HER2 DAB-precipitates width and color intensity. For scoring intensities 1+ and 2+ (grey), width and intensity show a linear correlation (r = 0.73, dashed lined). Scoring category 3+ shows saturated intensity (n = 1200 measurements in 40 cases per scoring category). (JPEG 585 kb
