1. A laboratory technique that uses antibodies to detect and identify specific proteins in a sample, typically after separating them by gel electrophoresis.
Usage: technical; biochemistry; also called Western blotting when referring to the most common variant

Examples

• The researchers used immunoblotting to confirm the presence of the target protein in the cell samples.
• Immunoblotting is a standard method for validating results from other protein detection techniques.
• The lab performed immunoblotting to measure protein expression levels across different treatment groups.
• Immunoblotting requires careful handling of antibodies to ensure accurate and reproducible results.
• Scientists rely on immunoblotting to detect biomarkers associated with disease progression.
