Amino acid determination has important applications in many biochemical and biomedical research studies. For example, it can be used to determine the amino acid composition of proteins, helping researchers to understand the structure and function of proteins. Additionally, amino acid determination can also be used to monitor the levels of amino acids in biological samples, which is important for studying the pathogenesis and treatment effects of various diseases.

Antibody drugs are a kind of biological preparations that use the mechanism of the immune system to specifically recognize and bind to specific targets in the body. They are widely used in the treatment of various diseases, such as cancer, autoimmune diseases, and infectious diseases. Due to their importance in clinical treatment, it is crucial to ensure the quality, purity, activity, and safety of antibody drugs. Micro-Flow Imaging (MFI) technology plays a crucial role in this regard.

Circular Dichroism (CD Spectroscopy) is a highly effective technique used for studying the structure and optical rotation of chiral compounds. This technique is based on the difference in the absorption of left and right circularly polarized light by chiral molecules, a difference that is reflected in the spectrum and can provide information about the molecular structure. Below are the basic principles and methods of measuring chiral compounds using CD Spectroscopy:

Circular Dichroism Spectroscopy (CD Spectroscopy) is a spectroscopic technique commonly used to study the structure of large biological molecules such as proteins, especially their secondary structure. CD Spectroscopy can provide important information about the local and global conformation of proteins, which is essential for understanding the function and stability of proteins.

CD Spectroscopy is based on the difference in the absorption of polarized light

The Differential Scanning Calorimetry (DSC) is an analytical technique used to study the thermal stability of proteins. This method can measure the thermal behavior of proteins when heated, especially the heat released or absorbed when their structure changes. DSC can provide vital information about protein folding and stability, which is invaluable in fields such as drug design, biotechnology, and disease research.

DSC works by comparing the difference in

The isoelectric point (pI) of a protein is the pH at which the protein is uncharged in solution, i.e., the point where the sum of the negative and positive charges of the protein is zero. At this pH value, the migration rate of the protein in an electric field is minimal. Determining the isoelectric point of a protein is very important for understanding its biochemical properties, purification strategies, and molecular recognition. The following are several commonly used techniques for measur

Infrared Spectroscopy (IR) is a powerful experimental technique often used in the fields of analytical chemistry and biology, especially in the study of biomolecular structure and function. It offers detailed information about molecular vibrations, which are related to the formation, length, and type of specific chemical bonds in molecules.

Infrared spectroscopy has wide applications in unraveling biomolecules:

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, infectious diseases, and more. Peptide drugs have specific biological activities and mechanisms of action, usually interacting with specific receptors or enzymes in the body to regulate physiological or pathological processes.

Fluorescence spectroscopy is an effective method for

Protein is the basis of life, performing most functions within cells and making up the main structural components of organisms. Meanwhile, amino acids, which can be considered the cornerstones of life, are the basic units that make up proteins.

Basic Structure of Amino Acids

Amino acids are organic compounds composed of an amino group (-NH2) and a carboxyl group (-COOH), both attached to the same carbon atom kno

Hydrogen/Deuterium Exchange Mass Spectrometry (HDX MS) is a powerful technique used to study the three-dimensional structure, folding, dynamics, and interactions between proteins or between proteins and other molecules. This method is based on the natural exchange phenomenon of hydrogen atoms with deuterium (an isotope of hydrogen) in the side chains of protein amino acid residues.

In a solvent containing deuterium, the hydrogen atoms in the amino acid resi
