In the past few years, progress has been made to allow the products of continuous crystallization to meet different requirements.
Purity and intrinsic rigidity are basic requirements for protein crystallization.
Approaches that use continuous crystallization to meet different quality requirements are summarized.
This chapter discusses some of the successful, currently practiced industrial control strategies and reviews the current understanding of relating process control technology to the requirements of automating crystallization processes.
Among the physico-chemical requirements for heme crystallization, a pH close to the heme pKa (4.8) is of foremost importance [16], [20], [27] and is close to the physiological pH of blood digestion in Hz-producing organisms [34], [35].
This paper will present latest achievements in high-power excimer laser and illuminator design to address the production requirements of thin film crystallization and will look at challenges to meet future requirements.
It is likely that the requirement for zinc for crystallization of Spy0129 results from its ability to rigidify these surface loops and thus permit stable crystal packing.
The X-ray structure of the bacterial protein yielded two pieces of information indispensable for the crystallization of eukaryotic Pur-α: the requirement of two PUR repeats interacting with each other to form a globular domain and a better delimitation of domain boundaries of the PUR repeats.
The switching speed, which is limited by its nucleation-dominated crystallization mechanism, is insufficient to satisfy the requirement of dynamic random access memory (around 10 ns) is also not satisfactory [7].
Also, PEG 300 significantly (p<0.05) reduced heme solubility in acidic conditions, re-inforcing the concept that initial solubilization is an important requirement to allow further heme crystallization in vitro.
