Fluid of fused spheres as a model for protein solution

  title={Fluid of fused spheres as a model for protein solution},
  author={Miha Kastelic and Yurij V Kalyuzhnyi and Vojko Vlachy},
  journal={arXiv: Soft Condensed Matter},
In this work we examine thermodynamics of fluid with "molecules" represented by two fused hard spheres, decorated by the attractive square-well sites. Interactions between these sites are of short-range and cause association between the fused-sphere particles. The model can be used to study the non-spherical (or dimerized) proteins in solution. Thermodynamic quantities of the system are calculated using a modification of Wertheim's thermodynamic perturbation theory and the results compared with…

Shielded attractive shell model again: resummed thermodynamic perturbation theory for central force potential
The approach developed earlier to describe the dimerizing shielded attractive shell (SAS) primitive model of chemical association is generalized and extended to include a description of a polymerizing SAS model based on the combination of the resummed thermodynamic perturbation theory for central force (RTPT-CF) associating potential and self consistent scheme.
Computational models for studying physical instabilities in high concentration biotherapeutic formulations
An overview of the different computational paradigms that have been successfully used in modeling undesirable physical behaviors of protein solutions with a particular emphasis on high-concentration drug formulations is provided.
Modeling phase transitions in mixtures of β-γ lens crystallins.
Evidence of the coexistence of three phases appears for the region of temperatures just out of the experimental range studied so far, and a large difference between the numbers of the attractive sites for γD and βB1 proteins is revealed.
