Proteins, or polypeptides, are organic compounds composed of amino acids. They are arranged in a linear chain and folded into globular form or other forms. Proteins are essential components of organisms and they participate in virtually every process within a cell. Many proteins are enzymes that catalyze biochemical reactions and are vital to metabolism. Not only are proteins a major structural component of living systems, they can also be effector molecules whose states determine downstream activities. Therefore, studying the protein characterization can reveal the mechanisms behind many of the cell’s responses to its environment. Given the vast number of applications for protein analysis, several tools and methods for its study exist; determining the correct method for your application is paramount to success.
Proteins differ from each other according to the type, number and sequence of amino acids that make up the polypeptide backbone. Hence, they have different molecular structures and physiochemical properties. Protein analysis technologies are used to understand the unique and complex relationships between proteins. They are utilized in various applications including biomolecular interactions, enzyme kinetics, heterogeneity applications, immunogenicity testing and affinity characterization. These applications are useful in the pharmaceutical, research and quality control industries. Some features to consider in selecting a protein analysis method are sample size and type, automation, ease of use, integrated software, binding parameters, data quality assessment and assay portability. Some protein analysis methods might be better suited for particular applications so be sure to inquire to guarantee the best fit for your project.
