The process involves separating proteins of different molecular weights via polyacrylamide gel electrophoresis (PAGE), transferring them onto a solid support (such as a PVDF membrane or nitrocellulose (NC) membrane), and then detecting the target protein using antigen-antibody reactions. Throughout the entire experimental process, every step—from sample preparation to antibody incubation—plays a crucial role in determining the experimental results.
