Protein Amino Acid Analysis: Techniques, Instruments, and Applications
What is Protein Amino Acid Analysis? Protein amino acid analysis is a technique for determining the type and amounts of amino acids in a protein sample, providing information on protein composition, post-translational modifications and overall protein quality. By gaining insight into amino acid content, researchers can assess protein purity, determine changes in amino acid composition, and ...

Protein-Protein Interaction Identification Method—Co-immunoprecipitation (Co-IP) and Pull-Down
Proteins control all biological systems in the cell. Although many proteins function independently, most proteins need to interact with other proteins to maintain complete biological activity. Therefore, in order to better understand the function and biological characteristics of intracellular proteins, researchers often need to identify and analyze protein-protein interactions. ...

Significance of Diagnostic Enzyme Detection
Serum enzyme tests have been used in clinical practice for a long time, such as increased amylase activity in serum and urine of patients with acute pancreatitis. In the 1930s, some scholars reported that the determination of serum lipase and alkaline phosphatase activities is helpful for the diagnosis of pancreatitis and bone diseases, respectively. After the 1950s, the application of serum ...

Principles, Advantages and Disadvantages of Edman Sequencing
What is Edman Degradation Sequencing? Edman degradation sequencing is to sequentially cut out each amino acid at the N-terminal of the protein through chemical reaction and then use HPLC liquid chromatography to identify the ID of the amino acid, and the obtained amino acid sequence information is the sequence of the N-terminal of the protein. Next, we use the determination of the first amino ...

GST-Pull Down Technology
Introduction to protein interactions The functioning of biological systems is inextricably linked to protein-protein interactions, and important biological processes such as DNA synthesis, gene transcriptional activation, protein translation, modification and localization, and information transfer all involve the role of protein complexes. Therefore, it is particularly important to discover and ...

Everything You Want to Know About Horseradish Peroxidase
Peroxidase, usually derived from horseradish, is a common enzyme used in clinical testing reagents. It is widely used not only in several biochemical assays but also in immunoassay (ELISA) kits. As a key component of the color development system of several kits, peroxidase has an important impact on the quality of the kits. Horseradish peroxidase (HRP) is the most commonly used enzyme because ...

Lactobacillus paracasei KBL382 administration attenuates atopic dermatitis by modulating immune response and gut microbiota
ABSTRACT Administration of probiotics has been linked to immune regulation and changes in gut microbiota composition, with effects on atopic dermatitis (AD). In this study, we investigated amelioration of the symptoms of AD using Lactobacillus paracaseiKBL382 isolated from the feces of healthy Koreans. Mice with Dermatophagoides farinaeextract (DFE)-induced AD were fed 1 × 109 CFU ...

Associations between perfluoroalkyl compounds and immune and clinical chemistry parameters in highly exposed bottlenose dolphins (Tursiops truncatus)
Perfluoroalkyl compounds (PFCs) are ubiquitous, persistent chemical contaminants found in the environment, wildlife, and humans. Despite the widespread occurrence of PFCs, little is known about the impact these contaminants have on the health of wildlife populations. We investigated the relationship between PFCs (including Σperfluorocarboxylates, Σperfluoroalkyl sulfonates, perfluorooctane ...

Effects of tobacco (smoking and snuffing) in type 2 diabetic patients
The present study aimed to evaluate the effects of tobacco on different biochemical and physical parameters in type 2 diabetic subjects from Dera Ismail Khan, NWFP, Pakistan. A total of 100 chronic type 2 diabetic patients of different age and sex with no tobacco addiction and with tobacco addiction were requested to volunteer their complete biodata on a given Performa. Blood biochemical ...
