B2R / SIMULATED WESTERN BLOT HANDOFF All numbers are synthetic. Bands are illustrative and are not used to derive measurements. ROI area: 100 pixels. Mean background: 30 arbitrary units per pixel. Corrected target = target raw - 3,000. Corrected control = control raw - 3,000. Ratio = corrected target / corrected control. Relative value = ratio / mean of the three Group A ratios. Six simulated samples, two groups. Biological/technical replicate identity unspecified. No error bars, p-values or inferential statistical claims. An actual project requires original images, lane mapping, exposure/linearity review, ROI and background review, valid loading-control selection, and a confirmed experimental design. No assessment here establishes that real experimental images can be quantified reliably.
