• • Optical Rotation Determination of Polypeptide Drugs

  Peptide drugs are biologically active protein fragments composed of short chains of amino acids. They play an important role in modern medicine and drug development due to their high efficacy, specificity, and relatively low toxicity and immunogenicity. They have shown great potential in treating various diseases such as cancer, autoimmune diseases, infectious diseases, and metabolic disorders.

• • Fluorescence Spectroscopy Analysis of Peptide Drugs

  Peptide drugs refer to short protein chains synthesized using specific amino acid sequences, which have the potential to treat various diseases such as cancer, autoimmune diseases, and infectious diseases. Peptide drugs have specific biological activity and mechanisms of action, usually interacting with specific receptors or enzymes in the body to regulate physiological or pathological processes.

• • Amino Acids: The Building Blocks of Life

  Proteins are the foundation of life, as they carry out most functions within cells and make up the main structural components of organisms. Meanwhile, amino acids are the basic building blocks of proteins and can be considered as the cornerstone of life.

• • Infrared Spectrum Spectrogram Analysis

  IR spectrum is created by analyzing the pattern of infrared light absorbed by a substance, which corresponds to the vibrations of chemical bonds and functional groups in molecules. In the analysis of biological structures, IR spectroscopy is an extremely valuable tool as it provides detailed information about the structure of biomolecules.

• • Conservation Analysis of Amino Acid Sequences: Key Insights into Protein Function

  Conservation analysis of amino acid sequences aims to determine the similarity between proteins or other amino acid sequences in different species or family members. This analysis can reveal which amino acid residues are important for function or structure, as these residues have been conserved throughout the evolution process.

• • Structural Analysis of Bovine Serum Albumin: Application of Circular Dichroism

  Bovine Serum Albumin (BSA) is a commonly used standard protein in biological experiments, which is the main protein component isolated from bovine serum. Due to its abundant presence and stable characteristics, BSA is often used as a control standard in experiments, such as protein concentration determination, enzyme-linked immunosorbent assay (ELISA), and other biochemical and molecular biology techniques.

• • Analyzing BLAST Protein Sequence Alignment Results

  BLAST (Basic Local Alignment Search Tool) is a widely used tool for aligning protein or nucleotide sequences. It can be used to search for homologous sequences of a target sequence in a known database, enabling sequence similarity analysis, which is crucial for protein function identification, family classification, and evolutionary research.

• • Multi-Method Approaches for Collagen Quantification and Analysis

  Collagen is an important structural protein that is widely present in the skin, bones, tendons, ligaments, and other tissues of the human body. It is crucial for maintaining the integrity and functionality of tissues. Determining collagen levels can help researchers and doctors understand the pathological processes of related diseases such as osteoporosis, arthritis, and skin aging, as well as contribute to drug development and other biomedical research.

• • 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.
