Membrane Crystallization

2019
Membrane crystallization is an innovative process, alternative with respect to conventional crystallizers. Due to its specific operational principles, based on the use of diffusive transport through polymeric membranes as the means to generate supersaturation and to induce heterogeneous nucleation phenomenon, a membrane crystallizer has the potential ...

Strategies for crystallizing membrane proteins

Journal of Bioenergetics and Biomembranes, 1996
Crystallizing membrane proteins remains a challenging endeavor despite the increasing number of membrane protein structures solved by X-ray crystallography. The critical factors in determining the success of the crystallization experiments are the purification and preparation of membrane protein samples.

Liquid Crystal Polymer Membranes

2015
Liquid crystals (LCs) combine properties of both liquids and crystals and can be organized in a variety of nanostructured polymer films with a monolithic structure. Therefore, polymer-based LCs are ultimately suited as membrane with an accurately controlled nanoporosity.

Membrane-Assisted Crystallization Technology

2013
The interest for crystallization processes based on membrane technology has steadily increased over recent years. This has primarily been driven by the unique opportunity such processes provide to control supersaturation rates and the influence they exert on the nucleation stage through a proper regulation of morphological and chemico-physical ...

Membrane Crystallization and the crystallizer of the future

2006
The opportunity to couple membrane processes and crystallization operations, in order to develop an efficient crystallization technology, has been proposed in the form of a membrane crystallizer (MCr). In this system, microporous hydrophobic membranes act as the physical support for contacting two liquid subsystems differing in temperature and/or ...

Membrane Crystallizer

2001
Well-controlled crystallization is the best method for preparing materials that are extremely pure. Furthermore, it can also be highly advantageous by operating the crystallization so that the crystals pick up impurities from water. Crystal growth generally starts at solute concentrations at which the nucleation occurs; the growth rate, depending on ...

Crystallization of intrinsic membrane proteins

Journal of Bioenergetics and Biomembranes, 1984
After many years of discouraging failures, it is now possible to crystallize the intrinsic membrane proteins and to obtain structural information from diffraction studies on the crystals. The strategy for the crystallization consists of depletion of boundary phospholipids from the protein and complex formation with specific ligands.

Crystallization of membrane proteins in Cubo

2002
Our understanding of lipidic cubic phases for the crystallization of membrane proteins has advanced greatly since the inception of the concept in 1996, and the method is becoming well accepted. Several protocols that allow the efficient screening of crystallization conditions and handling of crystals are presented.
