Crystallization of lysozymes induced by temperature lowering has been monitored by dynamic light scattering from the onset of supersaturation to the growth of protein crystals up to a noticeable size (150–200 μm). The apparent size of the scatterers was found to increase up to a maximum value as supersaturation proceeded, then to decrease down to its initial value. Apparitions of crystals (20–30 μm) were observed during this decrease. Light scattering is thus proved to be a sensitive technique to follow protein crystallization and to provide useful information on the process.

Abstract Crystallization conditions for hen egg white lysozyme in the presence of various ions were determined at pH 4.5 and 18 degrees C. The corresponding solubility curves show that the main effects are due to anions in the following order: SCN- greater than NO3- greater than Cl- greater than citrate2- greater than CH3COO- approximately H2PO4- greater than SO4(2-). This is in the reverse order of the lyotropic series of Hofmeister. As a consequence, SCN- precipitates and crystallizes lysozyme...

Abstract The concentration changes which accompanied the crystal growth of hen egg-white lysozyme from its aqueous solution were followed optically at 5, 10, 15, 30, 42, and 50°C for 30–360 days in the presence of 1–7% NaCl. When the initial protein concentration was selected so as to start the crystallization within a reasonable time and with a proper number of nuclei, the supernatant concentration approached constant values after 1–1.5 month, which were regarded as solubility ( S ) of the crys...

A simple theory is developed that accounts for many of the observed physical properties of micelles, both globular and rod-like, and of bilayer vesicles composed of ionic or zwitterionic amphiphiles. The main point of departure from previous theories lies in the recognition and elucidation of the role of geometric constraints in self-assembly. The linking together of thermodynamics, interaction free energies and geometry results in a general framework which permits extension to more complicated ...

Abstract Human labor still play an important role in cane sugar crystallization process. Automation control is essential to reduce human labor. An accurate image classification system is the basis for automation control of the cane sugar crystallization process. This paper builds a deep learning framework based on deep convolutional neural networks(DCNNs) to classify cane sugar crystallization image of cane sugar crystallization process for sugar factory. Different networks were trained on a lar...

Small-angle X-ray scattering (SAXS) analysis of biomolecules is increasingly common with a constantly high demand for comprehensive and efficient sample quality control prior to SAXS experiments. As monodisperse sample suspensions are desirable for SAXS experiments, latest dynamic light scattering (DLS) techniques are most suited to obtain non-invasive and rapid information about the particle size distribution of molecules in solution. A multi-receiver four-channel DLS system was designed and ad...

Irreversible protein–protein aggregation is associated with several human maladies, including Alzheimer's disease, and poses a challenge to pharmaceutical formulation and preservation efforts. The existence of multiple agglomeration pathways that lead to different final morphologies complicates the ability to determine the aggregation fate of proteins under various reaction conditions. Using lysozyme (3 mg mL−1) as a model protein for dynamic light scattering and circular dichroism studies, we o...

Obtaining X-ray suitable crystals is to date the rate limiting step to solve the structure of biological macromolecules such as proteins at atomic resolution. Those Structures are required for the design of novel drugs and to understand the way biological systems work. Rationalization of crystallization by biophysical methods is a promising way to accelerate this process. Here Dynamic Light Scattering (DLS) was applied in order to develop novel methods for the rationalization of crystallization ...

In this study, a solution circulating apparatus was employed to control the aggregation of protein molecules in situ. The association state of protein molecules was controlled by injecting protein solutions, buffers, and solutes into the device while monitoring the heterodispersity of the molecular nanoaggregates by an apparatus of high-performance heterodyne-based dynamic light scattering. Further, a highly ordered association of protein nanoaggregates was induced that lead to the generation an...

In this paper, we demonstrate the feasibility of using in situ Dynamic Light Scattering (DLS) to monitor counter-diffusion crystallization experiments in capillaries. Firstly, we have validated the quality of the DLS signal in thin capillaries, which is comparable to that obtained in standard quartz cuvettes. Then, we have carried out DLS measurements of a counter-diffusion crystallization experiment of glucose isomerase in capillaries of different diameters (0.1, 0.2 and 0.3 mm) in order to fol...

An ultrasensitive and simple dynamic-light-scattering (DLS) assay for the sequence-specific recognition of double-stranded DNA (dsDNA) was developed based on detection of the average diameter change of Au nanoparticle (AuNP) probes modified with oligonucleotides 5′-TTTCTCTTCCTT- CTCTTC-(T)12-SH-3′ (Oligo 1) and 5′-TTCTTTCTTTTCTTTTTC-(T)12- SH-3′ (Oligo 2). The target dsDNA was composed of two complementary oligonucleotides: 5′-AAAGAGAAGGAAGAGAAGAAGAAAGAAAAGAAAAAG-3′ (Oligo 3) and 3′-TTTCTCTTCCTT...
