Thermodynamics of retention for α-amylase in hydrophobic interaction chromatography
摘要
Abstract
The retention behavior for the denatured α-Amylase in hydrophobic interaction chromatography (HIC) was investigated. The results showed that the retention behaviors for α-Amylase were all well followed the non-linear Van′t Hoff equation. The calculated thermodynamic parameters in retention of α-Amylase showed that the retention of α-Amylase in HIC is driven by entropy, andΔH0, ΔS0 and ΔCP 0 linearly correlate both with the corresponding absolute temperatures and their reciprocals, respectively. The calculated folding free energy ΔΔGF of partially denatured α-Amylase on the stationary phase surface in HIC are much higher than that in solution, and the highest folding free energy is at 298K.关键词
