protein tagging

Protein tagging is a laboratory technique used to attach a specific marker or label to a protein, making it easier to detect, track, or isolate. Think of it like attaching a name tag or barcode to identify and study the protein in complex mixtures. Common tags include fluorescent molecules or small peptides. This helps scientists observe where the protein goes in a cell, measure its interactions, or purify it for further analysis, providing valuable insights into its function and behavior within biological systems.
