• • Peptide Spectrum Analysis

  Peptide spectrum analysis is a key concept in mass spectrometry, mainly used for the identification of proteins and their degradation products - peptides. In mass spectrometry analysis, protein samples are first hydrolyzed into smaller peptides by enzymes (such as trypsin), and then these peptides are analyzed by mass spectrometry.

• • Co-Immunoprecipitation Detection of Protein Ubiquitination

  Co-immunoprecipitation (Co-IP) is an experimental technique used to detect the interaction between a protein and other proteins. When it comes to detecting protein ubiquitination, Co-IP can be used to determine whether the target protein is ubiquitinated, and its interaction with ubiquitin protein.

• • What Is the Concept of Proteomics?

  Proteomics is a rapidly advancing field within molecular biology that focuses on the large-scale study of proteins, particularly their structures and functions. The term "proteome" refers to the entire set of proteins produced or modified by an organism or system. Proteomics encompasses various techniques to analyze the proteome, aiming to understand protein functions, interactions, and their role in biological processes.
