PMID: 22975958 DOI: 10.1007/978-1-62703-002-16 Abstract Electrophoresis and the following western blot analysis are indispensable to investigate biochemical changes in cells and tissues exposed to nanoparticles or nanomaterials. Areas covered: In this review, improvements in different areas of western blotting, including protein transfer and antibody validation, are summarized. With the latest advances in imaging software and instrument sensitivity, quantitative western blot analysis is now easier to achieve. Confirmation of Western blotting results via independent assays may provide biological verification or validation of an observed experimental effect. Western blotting combined with advanced digital imaging has become a powerful tool for measuring protein abundance and protein modifications. Recent reports suggest that a few key steps, such as the sample preparation method, the amount and source of primary antibody used, as well as the normalization method utilized, are critical for reproducible western blot results. An independent antibody-based assay may therefore use a different antibody to the one undergoing Western blotting validation. Since western blotting is a multistep protocol, variations and errors can occur at any step reducing the reliability and reproducibility of this technique. Western blotting is one of the most commonly used techniques in molecular biology and proteomics.
