Recovery and Purification of Protein Aggregates From Cell Lysates Using Ceramic Membranes: Fouling Analysis and Modeling of Ultrafiltration

Frontiers in Chemical Engineering, 2021
The characterization of membrane fouling provides valuable information about the performance and operational range of filtration processes. The range of operational parameters for the purification and concentration of protein aggregates from cell lysates

Conformational Changes Involved in the Switch from Ovalbumin to S-Ovalbumin

Zeitschrift für Naturforschung C, 1996
Abstract For the first time a comparative study on conformational differences between native oval­ buminand its heat-stable form, called S-ovalbumin. using small angle x-ray scattering, is reported. To detect a different pathway in the folding mechanism of the two proteins, scatter­ing measurements have been performed on ovalbumin and S ...

The Effect of Capparis spinosa on Inflammatory Responses in a Mouse Model of Allergic Asthma [PDF]

Research Journal of Pharmacognosy
Background and objectives: Allergic asthma is an inflammatory respiratory system disease. Capparis spinosa L. has been traditionally used to treat inflammatory diseases. Our goal was to examine the anti-inflammatory activity of C.

Structural Differences of Ovalbumin and S-Ovalbumin Revealed by Denaturing Conditions

Zeitschrift für Naturforschung C, 1997
We found, by circular dichroism and Raman spectroscopy measurements, that the secondary structure of the native ovalbumin and of its heat-stable form, called S-ovalbumin, is a probe of the structural differences between the two proteins. Small angle X-ray scattering and circular dichroism measurements performed on the two proteins under denaturing ...

In Vivo Monitoring of Thrombo‐Inflammatory Biomarkers via Molecularly Imprinted Polymer‐Integrated Hydrogel Microneedles

Advanced Materials, EarlyView.
A wearable electrochemical microneedle patch integrates Prussian Blue redox transduction with molecularly imprinted polymer recognition for reagent‐free sampling and detection of thrombo‐inflammatory biomarkers in dermal interstitial fluid. The platform tracks thrombin and inflammatory cytokines with sensitive in vitro, ex vivo, and in vivo performance,

Ovalbumin subfractionation and individual difference in ovalbumin microheterogeneity.

Journal of Biological Chemistry, 1981
Purified ovalbumin from hen egg white was fractionated by concanavalin A (Con A)/Sepharose chromatography. Four major fractions were separated, one unadsorbed fraction OA, followed by a minor fraction OA', and three adsorbed fractions OB, OC, and OD. The recovery was over 90%. Fractional ratios (OA:OB:OC:OD) were 16:6:37:41.

Ovalbumin is synthesized in mouse cells transformed with the natural chicken ovalbumin gene. [PDF]

Proceedings of the National Academy of Sciences, 1980
The entire chicken ovalbumin gene, accompanied by genomic DNA sequences flanking both termini of the gene and three copies of the herpes simplex virus thymidine kinase gene, has been cloned in plasmid pBR322. This recombinant plasmid was linearized and used to transform thymidine kinase-deficient mouse cells.

Biodegradable Chitosan Films as Green Resists for Gold Nanowires Fabrication Through AFM‐Based Nanolithography

Advanced Materials Interfaces, EarlyView.
Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

Reutilization of Food Waste: One-Step Extration, Purification and Characterization of Ovalbumin from Salted Egg White by Aqueous Two-Phase Flotation

Foods, 2019
For the purpose of reducing pollution and the reutilization of salted egg whites, which are byproducts of the manufacturing process of salted egg yolks and normally treated as waste, an aqueous two-phase flotation (ATPF) composed of polyethylene glycols (
