From Beginner to Pro: The Ultimate Western Blot Guide for Novices
Western blot (WB) is a routine yet powerful protein detection method used to study post-translational modifications, relative protein abundance, molecular weight, and protein-protein interactions. Since its inception, WB has provided valuable insights for academic research, diagnostics, and therapeutic testing.
As shown in Figure 1, WB separates native or denatured proteins via gel electrophoresis, transfers them to a membrane while preserving peptide integrity and biological activity, and uses specific antibodies to identify and quantify target proteins within complex mixtures extracted from cells or tissues.
