Abstract
Thermodynamic studies on protein adsorption onto chromatographic surfaces mainly focus on the molecular level interaction between proteins and ligands. Yet, not much attention is given to the study of polymer grafted ligand architecture effect on thermodynamic parameters, nor to the relation between chromatographic parameters and the directly obtained thermodynamic parameters. These relations are needed in order to confer meaning and to ease future data interpretation of thermodynamic studies of protein adsorption. In this study, the adsorption of bovine serum albumin monomer (BSAm) onto chromatographic surfaces with grafted ligands was studied from a thermodynamic point of view together with chromatographic data. Isothermal titration calorimetry (ITC) results showed that BSAm adsorption is exothermic (ΔH¯ads < 0) when adsorbs onto Toyopearl GigaCapQ 650 M, Toyopearl Q600AR, and Q Sepharose XL, but endothermic (ΔH¯ads > 0) when adsorbs onto Toyopearl SuperQ and a conventional resin (Q Sepharose Fast Flow), showing clear differences in the driving forces of adsorption caused by different ligand architectures. In addition, we found a new relation between the salt required for protein elution and the change in adsorption enthalpy (ΔH¯ads) directly measured with ITC, intrinsically connecting both adsorption and desorption mechanisms.

Abstract
We studied the adsorption mechanism of two basic proteins, equine cytochrome c (Cyt) and chicken egg-white lysozyme (Lys), adsorbing onto negatively charged chromatography surfaces. In liquid chromatography, the retention volume of Lys was larger than that of Cyt on negatively charged ion-exchange resins. When the temperature increased, the retention volume of Cyt increased, whereas that of Lys clearly decreased. Both Lys and Cyt share similar physical characteristics, so the opposite behavior with increasing temperatures was surprising, indicating a more complex mechanism of adsorption may be involved. We analyzed the adsorption of these proteins by using isothermal titration calorimetry (ITC). The change in adsorption enthalpy determined by ITC allowed the understanding of the reason for and underlying driving forces of protein adsorption that resulted in this opposite behavior. Large exothermic enthalpies of adsorption were observed for Lys (-43.95 kJ/mol), and Lys adsorption was found to be enthalpically driven. On the other hand, endothermic enthalpies were dominant for Cyt adsorption (32.41 kJ/mol), which was entropically driven. These results indicate that dehydration and release of counterions play a more important role in Cyt adsorption and ionic interaction and hydrogen bridges are more significant in Lys adsorption. Understanding of the adsorption mechanism of proteins onto chromatography resins is essential for modeling and developing new, efficient chromatographic processes.

Abstract
The thermodynamic of the adsorption of seven organic pollutants, namely benzotriazol, bisphenol A, caffeine, carbamazepine, diclofenac, ofloxacin, and pentachlorophenol, was studied on a microporous-activated carbon fabric. The isosteric adsorption quantities (Gibbs energy, enthalpy, and entropy variations) at high coverage ratio (around 1 mmol/g) have been determined from the adsorption isotherms at three temperatures (13, 25, and 40 °C). The adsorption heats at very low coverage (about 10-5 mmol/g) have been measured by flow micro calorimetry. The experimental adsorption energies were correlated to the adsorbate-adsorbent and the adsorbate-solvent interaction energies calculated by simulations using the COSMO-RS model. The main role of the van der Waals forces in the adsorption of the studied molecules was established. The bulkier the adsorbate is, the lower the adsorption Gibbs energy variation at high coverage deduced from the isotherms. The heterogeneity of the adsorption sites was brought out by calorimetric measurements. At high coverage, a physisorption phenomenon was observed. At very low coverage, high values of the adsorption heats were found (ranging from -58 to -110 kJ/mol), except for pentachlorophenol characterized by an athermal adsorption controlled by Pi-anions interactions.

Microcalorimetric study of adsorption and disassembling of virus-like particles on anion exchange chromatography media. J Chromatogr A 2015; 1388:195-206.

Abstract
Chromatographic purification of virus-like particles (VLPs) is important to the development of modern vaccines. However, disassembly of the VLPs on the solid-liquid interface during chromatography process could be a serious problem. In this study, isothermal titration calorimetric (ITC) measurements, together with chromatography experiments, were performed on the adsorption and disassembling of multi-subunits hepatitis B virus surface antigen virus-like particles (HB-VLPs). Two gigaporous ion-exchange chromatography (IEC) media, DEAE-AP-280 nm and DEAE-POROS, were used. The application of gigaporous media with high ligand density led to significantly increased irreversible disassembling of HB-VLPs and consequently low antigen activity recovery during IEC process. To elucidate the thermodynamic mechanism of the effect of ligand density on the adsorption and conformational change of VLPs, a thermodynamic model was proposed. With this model, one can obtain the intrinsic molar enthalpy changes related to the binding of VLPs and the accompanying conformational change on the liquid-solid interface during its adsorption. This model assumes that, when intact HB-VLPs interact with the IEC media, the total adsorbed proteins contain two states, the intact formation and the disassembled formation; accordingly, the apparent adsorption enthalpy, ΔappH, which can be directly measured from ITC experiments, presents the sum of three terms: (1) the intrinsic molar enthalpy change associated to the binding of intact HB-VLPs (ΔbindHintact), (2) the intrinsic molar enthalpy change associated to the binding of HB-VLPs disassembled formation (ΔbindHdis), and (3) the enthalpy change accompanying the disassembling of HB-VLPs (ΔconfHdis). The intrinsic binding of intact HB-VLPs and the disassembled HB-VLPs to both kinds of gigaporous media (each of which has three different ligand densities), were all observed to be entropically driven as indicated by positive values of ΔbindHintact and ΔbindHdis; while the nagative ΔconfHdis values suggested a spontenous enthalpy-driven process for the forming of HB-VLPs disassembled formation at all conditions studied. As ligand density increases, ΔconfHdis became more negative, which was in agreement with the findings from chromatography experiments, that higher ligand density leads to more serious disassembling of HB-VLPs. Results from thermodynamic studies provided us insight understanding on the mechanism of adsorption and conformational change of VLPs, as well as the effect of ligand densities on the structural stability of VLPs during IEC process.
