3.4.6. Thermal Stability Studies of HSA and the HSA-QTP System

The thermal stability of HSA without and with QTP was investigated using fluorescence measurements. The fluorescence spectra of the HSA (5 µM) and HSA-QTP (50 µM) complex were recorded (300–400 nm upon excitation at 295 nm) in the temperature range 25–80 ◦C (with 5 ◦C intervals). The solution mixture (HSA-QTP) was incubated for 1 h at 25 ◦C before fluorescence measurements.
