• • Exploring Mass Spectrometry Software in Peptide Mass Studies

  Peptides are biopolymers composed of amino acids and possess wide-ranging biological activities and pharmacological applications. In the field of biopharmaceuticals, the research and development of peptide drugs have become a hot research direction. Mass spectrometry analysis of peptides is an indispensable part of peptide research.

• • Principle of Quantitative Tyrosine Phosphoproteomics Analysis

  Tyrosine phosphorylation is a pivotal molecular event in intracellular signaling, regulating critical cellular processes such as proliferation, differentiation, metabolism, and survival. Controlled by tyrosine kinases and phosphatases, tyrosine phosphorylation plays a central role in understanding signal transduction pathways.

• • Detection of Antibodies Using PCR Based Sequencing

  Antibodies are essential protein molecules in the immune system that specifically recognize and neutralize foreign pathogens. Traditional antibody detection methods, such as Enzyme-Linked Immunosorbent Assay (ELISA) and Immunofluorescence Assay (IFA), are widely used but have limitations in sensitivity, specificity, and result interpretation.

• • Steps of De Novo Protein Sequencing Based on Mass Spectrometry

  De Novo protein sequencing involves deducing the amino acid sequence of a protein directly from mass spectrometry data without any reference sequence. This process is intricate and meticulous. 

• • Detection of Protein Mutations Using High-Resolution MS

  Protein mutations play a significant role in biological research. Mutations can lead to changes in protein function, affecting physiological and pathological processes in organisms. Traditional methods for detecting protein mutations include Sanger sequencing and next-generation sequencing (NGS), which, despite their high accuracy and sensitivity, have limitations in complex protein samples.

• • High-Resolution Mass Spectrometry-Based De Novo Peptide Sequencing

  As proteomics research progresses, understanding protein structures and functions becomes crucial for elucidating biological processes. In this context, peptide sequencing is a vital method for analyzing protein structures. Traditional peptide sequencing methods rely on database matching, which is limited when dealing with unknown protein sequences.

• • Nano-LC-Based Analysis of De Novo Peptide Sequencing

  Proteins play diverse roles in biological organisms, from enzymes catalyzing chemical reactions to structural components of cells.
