Western Blot Antibodies

Western Blot Antibodies are antibodies for immunoblotting applications, capable of recognizing linear epitopes under denaturing conditions to enable qualitative and semi-quantitative analysis of target proteins. Key experimental steps include blocking (5% non-fat milk or BSA to minimize non-specific binding), antibody dilution (primary antibody typically 1:1000–1:10000 for optimal signal-to-noise ratio), thorough washing (TBST to remove unbound antibodies), matched secondary antibody (HRP- or fluorophore-conjugated, species-specific), and loading control normalization (β-actin, GAPDH, etc.). Primary applications encompass protein expression analysis (validation of overexpression or knockdown efficiency), post-translational modification detection (phosphorylation, acetylation status), protein-protein interaction verification (detection of co-immunoprecipitated proteins), biomarker screening (differential expression of disease-associated proteins), and antibody quality control, serving as fundamental tools in molecular biology and protein research.
