• • Antibody Isoelectric Point Determination and Application in Biochemical Analysis

  The isoelectric point (pI) of an antibody is the pH at which the antibody does not migrate during electrophoresis. At this pH, the positive and negative charges of the antibody are balanced, resulting in an overall neutral charge. Determining the pI is important for understanding and analyzing proteins, especially antibodies, as it can affect their stability, solubility, and biological activity.

• • Exploring Cutting-Edge Techniques in Protein Sequencing: From Basics to Applications

  Determining the amino acid sequence of a protein is the basis for understanding its function, structure, and interactions. This process involves a series of techniques, each with its unique advantages and limitations.

• • Phosphoproteomics Sequencing: Efficient Analysis of Protein Phosphorylation

  Phosphoproteomic sequencing is a high-throughput technique used to study protein phosphorylation modifications. It can help researchers identify and quantify phosphorylation sites in proteins, providing a better understanding of cellular signal transduction, metabolic pathways, and disease mechanisms.

• • Peptide Sequence Identification: Efficient Analysis of Protein Structure and Function

  Proteins are the fundamental building blocks of life and play crucial roles in cellular functions, metabolism, and signal transduction. To gain a deeper understanding of biological processes and disease mechanisms, scientists need to understand the structure and function of proteins. Peptide sequencing technology has become an indispensable tool in biological research, providing a highly efficient method for deciphering protein structure and function.

• • De Novo Protein Sequencing: Efficient New Protein Analysis

  Protein is the foundation of the biological system, performing various biological functions including signal transduction, enzyme catalysis, cell structure, and immune system.

• • Endogenous Fluorescence Detection of Recombinant Protein Vaccines

  Recombinant protein vaccines are prepared by expressing and purifying the pure antigen protein of the pathogen in engineered cells (such as bacteria, yeast, mammalian, and insect cells) using genetic engineering technology. Compared to other types of vaccines, recombinant protein vaccines have higher costs but significantly better safety.

• • AUC Analysis of Antibody Drugs

  Antibody drugs are a class of drugs that are synthesized artificially using antibodies to treat diseases. They work by specifically binding to target molecules to achieve therapeutic effects. Common types of antibody drugs include monoclonal antibodies, artificially synthesized antibody fragments, immunotoxins, and antibody-drug conjugates.

• • Endogenous Fluorescence Detection of Recombinant Protein Drugs

  Recombinant protein drugs are protein-based therapeutic drugs produced using DNA recombinant technology or other biotechnological methods. Recombinant protein drugs include cytokines, peptide hormones, recombinant enzymes, monoclonal antibodies, fusion proteins, etc. Compared to traditional small molecule drugs, recombinant protein drugs have advantages such as high specificity, low toxicity, and significant therapeutic effects.

• • Determination of Recombinant Protein Drug Concentration

  Recombinant protein drugs refer to protein products derived from animals or plants through biotechnological research and development, which have certain biological activities and can prevent, treat, and diagnose diseases in humans, animals, and plants. Compared to small molecule drugs, protein drugs have advantages such as high activity, high specificity, and low toxicity, making them favored by researchers.

• • Precise Determination Methods for Collagen Protein Content

  Collagen is an important structural protein widely present in various biological tissues such as skin, bones, tendons, and blood vessels. Accurate determination of collagen content is crucial for biomedical research, disease diagnosis, and quality control of related products.
