Protein is the material basis of life and one of the most important biomacromolecules in living organisms. All life requires proteins. To understand proteins, we must first understand the properties of proteins. In addition to using protein analysis software to predict various parameters, we verify and analyze the isoelectric point, stability hydrophobicity and purity of proteins through advanced instruments and methods. We carry out comprehensive analyses of proteins to help customers further research the function and mechanism of proteins.
CD BioSciences has instruments and equipment with high resolution and sensitivity. We master a variety of protein predictive analysis methods. Our services cover the determination of a variety of protein properties, providing customers with the most reliable and efficient analytical services.
