Stability Analysis

Protein stability is critical in many in vitro protein studies and is considered to be the main requirement for functional studies involving natural and recombinant proteins. Therefore, when processing the target protein, it is very helpful to understand the stability of the protein and retain the natural conformation and normal function of the target protein. However, it is important to note that proteins are in a constantly changing state, and their structural and functional properties are easily affected by adverse conditions or sudden changes in their native environment. Sudden changes in temperature or pH, the presence of proteases, heavy metal ions, cell debris and other precipitated substances, lack of correct additives or mechanical agitation affect the stability of the protein and subsequently change its properties and functions. Therefore, the analysis of protein stability is very important. Now, CD BioSciences can provide you with professional stability analysis service. If you have any needs in this regard, please feel free to contact us.


▪ Differential Scanning Calorimetry (DSC)

This technique has been widely used in characterizing the stability of proteins in their native form by measuring the amount of heat required to denature a particular biomolecule (e.g., protein).

▪ Circular Dichroism (CD) Spectroscopy

CD spectroscopy provides information on the conformation and stability of proteins by measuring the differences in absorption between left- and right-handed polarized light resulting from the structural asymmetry of the protein of interest.

▪ Fluorescence-based Activity Assays

Basically, fluorescence-based activity assays can be used to indirectly measure protein stability and provide information on protein activity and functionality.
