• • Principle of Salivary Acid Detection for Cell Membrane

  Sialic acid is a type of terminal sugar residue widely present on glycoproteins and glycolipids on the cell membrane surface of animals, and it plays important biological roles. The principle of sialic acid detection on the cell membrane is based on the specific binding of certain molecules (such as lectins or antibodies) to cell surface sialic acid, followed by observation and analysis of this binding using appropriate detection methods.

• • Two-Dimensional Gel Electrophoresis Image Analysis

  Proteomics, the study of the proteome, requires advanced techniques for identifying and separating proteins. Two-dimensional electrophoresis (2-DE) is a cornerstone technology in this field, combining isoelectric focusing (IEF) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) to achieve high-resolution protein separation.

• • 2D Blue Native/SDS-PAGE Analysis

  The 2D Blue Native (BN)/SDS-PAGE technique is a powerful and sophisticated method for analyzing protein complexes. By combining Blue Native polyacrylamide gel electrophoresis (BN-PAGE) with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), researchers can gain comprehensive insights into the properties and compositions of protein complexes.

• • Overview of Methods for Identification of Collagen Protein

  Collagen is a widely present structural protein in animal tissues, especially in the skin, bones, tendons, ligaments, and many other connective tissues. Due to its crucial role in maintaining tissue structure and function, the identification of collagen is highly important for biomedical research and clinical diagnosis.

• • Protein Immunoblotting and Electrotransfer

  Protein immunoblotting, commonly known as Western Blotting, is a pivotal technique in molecular biology, biochemistry, and immunogenetics. This method is essential for detecting and analyzing specific proteins within a sample, providing valuable qualitative and semi-quantitative data.

• • Two Dimensional Gel Electrophoresis Service

  Two-dimensional gel electrophoresis (2-DE) is a crucial technique in proteomics, enabling the separation and analysis of complex protein mixtures from biological samples. This method separates proteins in two stages: isoelectric focusing (IEF), which separates proteins based on their isoelectric point (pI), and SDS-polyacrylamide gel electrophoresis (SDS-PAGE), which separates proteins by their molecular weight (Mr).

• • Protein Hydrolysis and Its Scientific Significance

  Protein hydrolysis is a significant topic in biochemistry, involving enzymatic reactions that break down proteins into peptides or amino acids. This process plays a crucial role in understanding protein structure and function, developing novel biomaterials, and advancing genetic engineering and pharmaceutical research. This article will introduce the basic principles of protein hydrolysis, the classification and applications of enzymes, and exemplify its importance in biomedical research.

• • 1D SDS-PAGE and IEF

  Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a fundamental technique extensively used in molecular biology and biochemistry for the separation and analysis of proteins. This method is invaluable in protein expression studies, providing detailed electrophoretic patterns of protein samples.

• • Advances in Proteomics

  Proteins are the direct executors of physiological functions, and studying their structure and function helps elucidate the mechanisms of changes under physiological or pathological conditions. Research on protein post-translational modifications, interactions, and conformations relies on direct protein studies. Therefore, a comprehensive understanding of life's complex activities necessitates studying proteins at a holistic, dynamic, and network level.
