Melting Point: Can Your Proteins Take the Heat?

Heating a protein beyond a critical temperature can cause it to lose its higher order structures.  In the concentrated regime, this molecular unfolding can result in gelation making viscosity measurements inappropriate for determining this transition. 


Even dilute solutions can exhibit local gelation if the proteins are able to migrate to a hydrophobic air interface, which is the case for traditional rotational rheometer or capillary viscometer experiments

VROC_initium_-1-1VROC® initium, our automatic, unattended viscometer, was used to obtain the data generated in this application note. VROC® initium prevents the formation of an interface and eliminates the possibility of locally concentrated proteins forming a gel.
