• • Detection of Binding Activity of Antibody Drugs

  The evaluation of binding activity of antibody drugs (such as monoclonal antibodies) is a key step in ensuring their efficacy and safety in the drug development and quality control process. Binding activity refers to the ability of an antibody to bind to its specific antigen. Here are some commonly used methods for evaluating the binding activity of antibody drugs:

• • Peptide Sequence Determination by MS-MS

  Peptide sequence determination is a core component of proteomics research, which involves the precise identification of protein or peptide sequences. MS-MS, also known as tandem mass spectrometry, is a powerful technique used to achieve this goal. This article will introduce the basic principles of peptide sequence determination, the working mechanism of MS-MS technology, and its applications in biomedical research.

• • N-Terminal Sequence Analysis of Platelet Proteins by MS

  Platelets, also known as thrombocytes or blood clot cells, are important components in human blood. They play crucial roles not only in coagulation and hemostasis but also in inflammation, immune regulation, and tumor formation and development. The protein composition and changes of platelets are essential for understanding these biological processes.

• • Metallic Elements in Fish Tissue

  In the field of food safety and nutritional science, precise analysis of metal elements in fish tissue is particularly important. MtoZ Biolabs uses cutting-edge technology to perform comprehensive detection and analysis of metal elements in fish tissue, providing important data support for researchers and industry experts.

• • How to Detect the Ubiquitination Level of a Protein

  Ubiquitination is a widely occurring protein modification that regulates the localization, activity, stability, and interactions of proteins, playing important roles in cellular functions and biological processes. Therefore, detecting the ubiquitination level of a protein is of great significance for understanding its function and regulatory mechanisms. This article mainly introduces how to detect the ubiquitination level of a protein.

• • Strawberry Fruit Protein Parallel Reaction Monitoring Analysis

  Strawberry fruit, as an important agricultural crop, not only has high economic value but also occupies an important position in people's daily diet. The quality of strawberries, including their color, aroma, taste, and nutritional components, is determined by their complex internal biological processes. Among them, proteins play a core role in regulating these biological processes.

• • Steps of Protein Interaction Mass Spectrometry Analysis

  Protein-protein interaction mass spectrometry analysis has become an indispensable tool in biological research, especially in the study of protein interactions. However, this complex technical process is not simple and requires careful execution by scientists and in-depth analysis of the results.

• • How to Perform Protein Spectrometry on Liquid Samples?

  How to perform proteomic analysis of liquid samples? Proteomic analysis is a key technique for understanding the functionality and dynamics of biological systems. Through proteomic analysis, we can study the structure and function of proteins, including their mass, sequence, modifications, interactions, and how they change over time and in different environments. Here are the steps involved in performing proteomic analysis of liquid samples.

• • Protein Affinity Purification Combined With Mass Spectrometry

  Affinity purification combined with mass spectrometry analysis is a powerful technique used to selectively isolate and purify specific target proteins or other biomolecules using special biological molecules such as antibodies or ligands. The general steps involved in affinity purification include solution preparation, sample preparation, sample loading, elution, and analysis.

• • What Parameters to Look for in GST Pull-Down Mass Spectrometry?

  In biological research, GST pull-down experiments are commonly used techniques for screening and identifying protein-protein interactions. Through this experiment, the target protein can be isolated from its potential interacting partners and further analyzed, such as using mass spectrometry for protein identification. When interpreting GST pull-down mass spectrometry analysis results, there are several important parameters to consider.
