• • Protein Peptide Drug Mass Spectrometry Analysis

  In the field of modern drug development, mass spectrometry analysis of protein peptides is a crucial step. This analysis not only helps to understand the molecular structure of drugs but also ensures their safety and efficacy. With the rapid development of biotechnology, protein peptides have become important means of treating various diseases, and mass spectrometry analysis provides necessary molecular-level information.

• • Protein Targeted Quantification

  Protein Target Quantification aims to accurately measure the abundance of specific proteins in biological samples. It has the advantages of high throughput, accuracy, and reproducibility. Using early data from differential proteomics/transcriptomics/genomics analysis, this method has validated biomarkers in large biological sample sizes.

• • Saliva Acid Detection Method

  Sialic acid, a common term for a type of 9-carbon sugar found in animal tissues and on the surface of glycoproteins and glycolipids, is crucial for diagnosing certain diseases (such as cancer), monitoring the stability of biomolecules, and drug development in the fields of biology and clinical medicine. Here are some commonly used methods for sialic acid detection.

• • Quantitative Cross Linking/Mass Spectrometry

  Quantitative Cross-Linking/Mass Spectrometry (XL-MS) combines the techniques of chemical cross-linking and mass spectrometry to study protein-protein interactions and their spatial structures.

• • How to Test the Content of Collagen Protein

  Testing collagen content typically involves biochemical analysis methods, which can be direct or indirect. Here are several commonly used techniques for testing collagen content.

• • How to Detect Collagen Protein

  Although collagen accounts for about 30% of the total protein in the human body, it can be difficult to purify and analyze due to the extensive network of collagen molecules formed by different types of cross-linking, which makes collagen insoluble and difficult to extract.

• • Detecting HCP Using WB Method

  HCP (Host Cell Proteins) are proteins produced by host cells that are used in the production of biopharmaceuticals and may contaminate the final therapeutic product. The detection and quantification of HCP is an important step in the development and production process of biopharmaceuticals, as HCP can have adverse effects on the safety, purity, and potency of the drug.

• • Infrared Spectroscopy Analysis Method

  Infrared spectroscopy is a commonly used method for analyzing the structure of substances. When molecules absorb infrared radiation at specific frequencies, their vibrational states change, resulting in an infrared spectrum. Through infrared spectroscopy, we can obtain information about the functional groups, structures, and other related properties of a substance.

• • Protein Phosphorylation Detection by GST in Vitro

  Extracellular GST (Glutathione S-Transferase) protein phosphorylation detection is an experimental method used to study the phosphorylation status of proteins. This method combines the purification technique of GST fusion proteins with phosphorylation status detection techniques to analyze the phosphorylation level of specific proteins or protein domains. Using this method, researchers can study the phosphorylation status of proteins under specific conditions of signal pathway activation or inhibition.

• • Class Generalization Level Inspection

  SUMO (Small Ubiquitin-like Modifier)ylation is an important protein post-translational modification process that involves the covalent attachment of SUMO proteins to specific lysine residues on target proteins. This modification is crucial for regulating protein localization, stability, activity, and involvement in processes such as cell cycle control, DNA damage repair, and signal transduction.
