In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Both thermal and chemical denaturation confirm that, all redesigned proteins, in agreement with the calculations, possess increased stability. One of the three mutations shifts the population in favor of the higher order oligomerization state in solution as shown by both size exclusion chromatography and native gel electrophoresis.
The conservation of the TIM barrel fold is mirrored by the conservation of its equilibrium and kinetic folding mechanisms in bacterial paralogs with phylogenetically distinct lineages. Chemical denaturation of several natural [27] [28] and 2 designed TIM barrel variants [28] invariably involves a highly populated equilibrium intermediate. The ...
Bruce Drysdale Elementary student is 1 of 8 national finalists in the 5th grade division of DAR's 'Stars and Stripes Forever' essay contest.
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.
On Dec. 7 at North Henderson High School, 11th grader Citlally Diaz, 17, was honored for winning one of just four $3,000 scholarship grand prize awards out of thousands of entries across the country.
A thermal shift assay (TSA) measures changes in the thermal denaturation temperature and hence stability of a protein under varying conditions such as variations in drug concentration, buffer formulation (pH or ionic strength), redox potential, or sequence mutation. The most common method for measuring protein thermal shifts is differential ...
Anaphylaxis is a “life-threatening allergic reaction that happens very quickly” and at its most severe stage, a person could “lose consciousness,” become “unable to breathe” and have ...
