Study of Secondary structure formation in peptides (CAT#: STEM-AC-0070-WXH)

Introduction

Secondary structure elements typically spontaneously form as an intermediate before the protein folds into its three dimensional tertiary structure. Secondary structure is formally defined by the pattern of hydrogen bonds between the amino hydrogen and carboxyl oxygen atoms in the peptide backbone.

Principle

The temperature jump method is a technique used in chemical kinetics for the measurement of very rapid reaction rates.
The T-Jump technique provides a means to follow fast reactions with half-lives of just a few microseconds. The reaction volume is prepared so that it is in equilibrium and then rapidly perturbed by a rapid change in temperature. There is a new equilibrium constant at the higher temperature, but the initial concentrations are balanced for the lower temperature. The system therefore relaxes and the reaction proceeds until the concentrations have reached their new equilibrium values.
