A common application involves verifying the successful knockdown of a target protein using siRNA or CRISPR-Cas9 gene editing. For instance, to study the insulin signaling pathway, a western blot example would involve probing a lysate from treated cells with an antibody specific to the phosphorylated (activated) form of Akt.

Analysis of Protein Isoforms and Size Variants The technique is also indispensable for analyzing protein isoforms or splice variants that differ in molecular weight. The membrane is then incubated with a primary antibody that specifically binds to the target protein, followed by a secondary antibody conjugated to an enzyme or fluorophore.
Monitoring Post-Translational Modifications Another critical use involves detecting post-translational modifications, such as phosphorylation, glycosylation, or ubiquitination, which often regulate protein function and cellular signaling pathways. This secondary antibody binds to the primary antibody, and a chemiluminescent, fluorescent, or colorimetric substrate generates a detectable signal, revealing the presence and relative abundance of the specific protein of interest.

This unique ability to verify protein size makes it an essential tool for validating results obtained through other high-throughput technologies. Unlike ELISA, which is typically performed in a 96-well plate format, western blotting provides information on the molecular weight of the target, confirming the identity of the protein and ruling out non-specific binding or degradation.
