Fig. 3: Concordance of Mean Pixel Intensity by MIBI-TOF.

A Representative MIBI-TOF images from serial sections of the same TMA core of lymph node tissue. B Plot of the average Mean Pixel Intensity (MPI) of all FOVs of the same TMA core vs. the MPI of each FOV. Each color represents a different marker. The gray line is a reference line with slope 1 and intercept 0. We performed least squares linear regression of the average MPI of the core vs. the MPI of all six serial sections and found the slope m (C) and coefficient of determination R2 (D) for all 16 markers.
