Western blotting denotes a multi-step analytical technique separating proteins by gel electrophoresis, transferring them to nitrocellulose or PVDF membranes typically 0.2–0.45 μm in pore size, and detecting targets via antibody-mediated chemiluminescence or fluorescence for qualitative and semi-quantitative analysis. The method serves fundamental protein validation, biomarker confirmation, and regulatory-compliant biologics characterization. Detection reagents and imaging systems capture the deepest margin pools as laboratories trade up from film-based chemiluminescence to near-infrared and fluorescence platforms. Electrophoresis equipment remains structurally mature, with replacement cycles extending as precast gel formats reduce instrument utilization. Academic institutions and pharmaceutical companies represent the most concentrated demand endpoints, though biotechnology firms are expanding fastest as cell and gene therapy pipelines proliferate.
