WebJan 14, 2024 · Unequal sample loading, in terms of the amount of protein per lane, can cause variation in signal intensities, which can lead to inconsistent results and inaccurate conclusions. To prevent loading variability from disrupting your data, it is important to measure the total protein concentration of each sample. WebWestern blot normalization allows you to faithfully compare changes in protein expression by establishing the baseline needed to correct against common errors such as inconsistent sample preparation, pipetting error, and uneven protein transfer.
