  • Protein Absolute Quantification Analysis

    Protein Absolute Quantification Analysis

    Protein Absolute Quantification Analysis Absolute quantification analysis is a crucial technique in the field of proteomics, specifically designed to accurately determine the concentration or copy number of proteins or peptides in a sample. The core of this method lies in the precise calibration using known concentrations of standards (usually isotopically labeled peptides). Absolute quantification analysis is of significant importance for both basic biological research and clinical applicati...
  • Targeted Proteomics Analysis

    Targeted Proteomics Analysis

    Targeted Proteomics Analysis Proteomics research can be classified into two branches based on whether its focus is specific to a certain class of proteins: targeted proteomics and untargeted proteomics. Targeted proteomics emphasizes precise and in-depth study of pre-defined target proteins, while untargeted proteomics aims to comprehensively detect all proteins in the sample, with the goal of discovering unknown protein types and potential biomarkers, and is therefore often referred to as di...

  • Serine/Threonine Post-Translational Modifications

    Serine/Threonine Post-Translational Modifications

    Serine/Threonine Post-Translational Modifications Serine and Threonine Post-Translational Modifications (PTMs) refer to the chemical modifications that proteins undergo after synthesis, with phosphorylation and glycosylation being the most common forms of modification. The PTMs on serine and threonine residues mainly include phosphorylation and O-glycosylation. After modification, these amino acid residues can significantly alter the protein’s activity, stability, and interaction capabi...

    Cysteine Post-Translational Modifications Omics Analysis

    Cysteine Post-Translational Modifications Omics Analysis Cysteine, with its remarkable reactivity, plays a pivotal role in protein structure and function. Serving as a nucleophilic reagent, redox catalytic center, metal ion ligand, and key site for conformational changes, it extensively participates in and profoundly influences protein activity and regulatory mechanisms. It’s worth noting that cysteine residues are prone to undergo various types of post-translational modifications (PTMs...
  • Protein Post-Translational Modification (PTM) Omics Analysis

    Protein Post-Translational Modification (PTM) Omics Analysis

    Protein Post-Translational Modification (PTM) Omics Analysis Over the past decades, researchers have discovered that the complexity of the human proteome far exceeds that of the genome. While approximately 20,000-25,000 human genes encode for over a million protein variants, this phenomenon arises from mechanisms such as gene recombination, selective transcription initiation, differential transcription termination, and splicing. Moreover, post-translational modifications (PTMs) play a crucial...
  • Identification of interaction regions for protein-protein and antibody-antigen interactions

    Identification of interaction regions for protein-protein and antibody-antigen interactions

    Identification of interaction regions for protein-protein and antibody-antigen interactions A profound understanding of protein structure and its interactions is crucial for revealing their biological functions. However, due to the complexity and diversity in the field of proteins, a single research technique often struggles to fully elucidate their mysteries. Therefore, biologists typically adopt a strategy of integrating multiple technical approaches to collectively explore the three-dimens...
