Label Free shotgun proteomics is a high-throughput protein identification and quantification technique that combines liquid chromatography (LC) with high-resolution mass spectrometry (MS) to analyze the protein composition and relative expression levels in complex biological samples, all without the need for external labeling. The "shotgun" approach utilizes random enzymatic digestion to generate peptides, which are then directly separated and detected in the peptide mixture. This strategy greatly enhances both experimental efficiency and the depth of analysis, providing a comprehensive overview of the proteome.
Label Free shotgun proteomics offers a powerful solution to the challenge of detecting proteins across a wide dynamic range, especially low-abundance proteins, by leveraging its high sensitivity, broad coverage, and efficient peak intensity-based quantification via mass spectrometry. The absence of labeling significantly reduces experimental costs, streamlines workflows, and is especially suitable for large-scale analyses across multiple sample conditions. This technique enables in-depth proteomic analysis, providing robust data for studying molecular mechanisms, investigating disease-associated protein alterations, and discovering potential biomarkers.
