Crystallization of Membrane Proteins

2013
The crystallization of membrane proteins is an essential technique for the determination of atomic models of three-dimensional structures by X-ray crystallography. The compositions of solutions of purified membrane proteins are altered, so as to transiently induce supersaturation, a requirement for crystal nucleation and growth.

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 of salt crystals: membrane modeling

2018
Crystallization is one of the most widely applied separation processes in the chemical industry and the interest to combine membrane operations and crystallization has increased recently. Membrane crystallization (MCr) is emerging as a promising technique with some important advantages with respect to traditional crystallization processes: well ...

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 ...

Crystallization of membrane proteins

Trends in Biochemical Sciences, 1983
Abstract After a long period of fruitless attempts, three-dimensional crystal of membrane proteins are now available. The best of the crystals are suited for high-resolution structure determination by X-ray crystallography. The use of small detergents and small amphiphilic molecules during crystallization proved to be of great value.

Continuous Membrane Crystallization

2020
Membrane processes meet the requirements of Process Intensification since they have the potential to replace conventional energy-intensive techniques, to accomplish the selective and efficient transport of specific components, and to improve the performance of reactive processes.

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 ...

Membrane Crystallization and Membrane Condenser: Two Membrane Contactor Applications

Journal of Chemical Science and Chemical Engineering, 2020
In recent years different new membrane processes have been designed and developed. In this paper two innovative processes (i.e., membrane condenser and membrane crystallization) will be described and discussed. Membrane crystallization can be used in desalination in combination with membrane distillation and pressure driven membrane processes (such as ...

Crystallization of Integral Membrane Proteins

Current Protocols in Protein Science, 2007
AbstractOver the last 20 years, the use of X‐ray crystallography has become a viable technique for the structure determination of integral membrane proteins. However, standard crystallizaton protocols must be modified to account for difficulties involved in handling membrane proteins, which arise primarily from having detergent present.
