Protein Folding Imaging Analysis
Protein is a complex organic compound composed of amino acids. Due to the hydrophilicity, hydrophobicity, positive charge, negative charge and other characteristics of amino acid residues, it can be folded into a precise 3D structure through the interaction between the residues. The sequence of amino acids determines the unique 3D structure of each protein and its specific functions. Protein participates in almost every process in the cell and is necessary to maintain the structure and function of human tissues and organs. Protein folding errors can induce a variety of degenerative diseases, such as Parkinson's disease, Alzheimer's disease, frostbite, and senile heart failure. Therefore, imaging analysis of the folding process of proteins is of great significance for the early diagnosis and treatment of diseases.

Protein Folding Imaging Analysis
Most proteins must be folded into a unique three-dimensional structure to perform their biological functions. However, in the cellular environment, newly synthesized proteins may misfold and form toxic aggregates. To ensure effective folding, it is necessary to monitor the dynamic process of protein folding in real time. Fluorescence imaging technology provides a useful and reliable method for elucidating the mechanism of protein folding and aggregation.
CD BioSciences has been committed to the research and development of fluorescent probes and imaging technology for many years. We can provide you with folded protein covalent probes to visually analyze protein dimerization, interaction and conformational changes. Understanding the dynamic process of protein folding and aggregation can help you diagnose and treat diseases caused by protein folding errors.
