Protein denaturization by heat denaturation is the process of modifying the conformation of the protein structures without rupturing the native peptide linkages. Recently, we reported a unique approach to preserve the activity of some proteins in the presence of the denaturing agent, sodium dodecyl. Introduction: denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures since denaturation reactions.

We showed that the taylor dispersion analysis (tda) is a fast and easy to use method for the study of denaturation proteins we applied tda. The i-domain is an insertion domain of the bacteriophage p22 coat protein that drives rapid folding and accounts for over half of the stability of the full-length.
