• • Application of Top-Down Proteomics in PTM Detection

  Proteomics, the comprehensive study of proteins within a biological system, is a critical branch of the post-genomic era, offering essential tools to uncover the essence of life processes. N-terminal degradation, a method of protein modification and degradation, holds significant promise within proteomics.

• • Workflow of Top-Down Proteomics for Protein Analysis

  Top-Down Proteomics is a strategy in proteomics that involves the direct analysis of intact proteins. Unlike traditional Bottom-Up Proteomics, which requires the digestion of proteins into peptides, Top-Down Proteomics preserves the protein's original form, making it particularly suitable for studying post-translational modifications, protein isoforms, and protein complexes.

• • Advantages and Disadvantages of Top-Down Proteomics

  Top-down proteomics, as an advanced methodology, has carved out a niche for itself in the field of proteomics by offering insights that other techniques may miss. However, the complexity and limitations associated with this approach warrant a deeper understanding of its practical applications and potential areas for improvement.

• • Principle of Top-Down Proteomics in Protein Characterization

  Proteomics studies the structure and function of the proteome—an organism's complete set of proteins. With advancements in biotechnology, proteomics has made significant strides in understanding protein structures, functions, and interactions. Among the methodologies in proteomics, Top-Down Proteomics has gained prominence for its ability to directly analyze intact proteins.

• • Protein Interaction Experiment Analysis: From Sample Preparation to Interaction Identification
