Mol Omics. 2020 Dec 1;16 (6):573-582. doi: 10.1039/d0mo00087f. Epub 2020 Sep 24. Abstract. Chemiluminescent western blotting has been in common practice for over three decades, but its use as a quantitative method for measuring the relative expression of the target proteins is still debatable. This is mainly due to the various steps, techniques, reagents, and detection methods that are used to obtain the associated data.

To answer this, use the following steps: Identify the initial value and the final value. Input the values into the formula. Subtract the initial value from the final value, then divide the result by the absolute value of the initial value. Multiply the result by 100.
