    • • Mass Spectrometry Protein Sequencing

      Mass spectrometry protein sequencing is a core technology in modern biology, pharmacy, and medical research. It utilizes mass spectrometers to precisely analyze proteins, revealing their molecular structures, amino acid sequences, and modification states. As a powerful analytical tool, mass spectrometry protein sequencing offers several key advantages. Firstly, mass spectrometry has exceptional sensitivity, enabling the detection of extremely low-abundance proteins in complex biological samples. Secon......

    • • HCP Analysis

      HCP analysis is a technique used to detect and quantify residual host cell proteins in biopharmaceutical production. Host cell proteins are byproducts produced alongside the target recombinant protein during its expression in host cells. The main goal of HCP analysis is to detect and quantify these proteins, ensuring the purity of biopharmaceutical products and reducing potential risks to human health. In particular, HCP contamination in the production of biopharmaceuticals can lead to adverse effects......

    • • Identification Protein

      Identification Protein refers to a series of experimental techniques used to identify and determine the types, quantities, functions, and modifications of proteins present in a sample. Proteins are essential mediators of various biological activities inside and outside the cell, and nearly all cellular functions require the involvement of proteins. Therefore, accurate identification protein, especially in complex biological samples, provides valuable information that aids scientists in understanding t......

    • • Overview of Phosphoproteomics Analysis

      Phosphoproteomics analysis is a pivotal technique for investigating protein phosphorylation and its regulatory roles in biological systems. As one of the most prevalent post-translational modifications, phosphorylation governs essential cellular processes, including signal transduction, metabolism, cell cycle progression, gene expression, and apoptosis. By systematically profiling phosphorylated proteins, researchers gain insights into cellular responses to external stimuli, regulatory mechanisms unde......

    • • TMT Quantitative Proteomics

      TMT quantitative proteomics is a highly efficient protein quantification technique widely utilized in biological and medical research. By precisely quantifying protein abundance across samples, it reveals molecular changes within complex biological systems. This approach employs chemical labeling reagents to tag peptides from different samples with distinct isobaric mass tags, enabling simultaneous identification and quantification via mass spectrometry (MS). Compared to conventional protein quantific......

    • • 2D-DIGE in Proteomics Analysis

      Two-dimensional difference gel electrophoresis (2D-DIGE) is a widely employed technique in proteomics, designed to efficiently and accurately compare protein profiles across different samples. By combining two electrophoretic principles—Isoelectric Focusing (IEF) and Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE)—this method allows simultaneous analysis of multiple protein samples on the same gel, enabling high-resolution separation and quantitative analysis. 2D-DIGE is particula......

    • • Olink Analysis

      Olink analysis is a high-throughput immunoassay platform technology designed for rapid and precise protein quantification. Leveraging Olink's unique Proximity Extension Assay (PEA) technology, researchers can simultaneously detect hundreds to thousands of protein biomarkers, significantly accelerating biomarker discovery and validation. PEA employs two antibodies that bind to the target protein, one carrying an extension probe. Upon binding, the probes form a complete DNA sequence, which is then detec......

    • • Glycan Analysis of Monoclonal Antibody

      The glycan analysis of monoclonal antibody is a crucial research area in biopharmaceuticals and biotechnology. Monoclonal antibodies are highly specific therapeutic proteins widely used to treat diseases such as cancer, immune disorders, and infectious diseases. This analysis focuses on detailed characterization of glycosylation patterns, a type of post-translational modification present in both the constant and variable regions of antibodies. Glycosylation profoundly influences antibody structure, st......

    • • Label-Free Quantification

      Label-Free Quantification is a widely used technique in proteomics that directly measures the relative abundance of proteins in a sample using mass spectrometry, eliminating the need for chemical or isotope labels. This approach relies on detecting and comparing signal intensities across different conditions to infer protein abundance. Its simplicity and versatility have made it an essential tool across biomedical research, drug development, disease mechanism studies, and agricultural science.   In bi......

    • • Identify Protein

      To identify protein is to accurately detect and characterize specific proteins within biological samples using advanced technical methodologies. The ability to identify protein is fundamental to understanding their biological functions, as protein activity and function are intrinsically tied to their structure and molecular interactions. This process is not merely about confirming the presence of proteins but also serves as the basis for comprehending their biological roles within cellular contexts. A......
