Isothermal Titration Calorimetry Flashcards
1
Q
Components ITC
A
Reference cell
Sample cell
Syringe containing titrant (ligand)
2
Q
Principle ITC
A
Heat of binding protein-ligand
- heat absorbed: endothermic
- heat released: exothermic
Maintainf Delta T bw cells = 0
Quantity of heat(Q) applied to reference cell = amount binding
