Diffusion of globular proteins in a Sephadex G200 gel bead

, 2005
We measured FRAP curves of solutions of globular proteins fractions labeled with fluorescein and included in a Sephadex G 200 single gel bead. We determined the diffusion coefficient D of these macromolecules in the gel.

UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

Pest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium

VALUE OF THE SEPHADEX GEL FILTRATION TEST IN ASSESING THE RISK OF BILIRUBIN ENCEPHALOPATHY IN JAUNDICED NEWBORNS

, 1985
IT IS THE PURPOSE OF THIS STUDY TO INVESTIGATE WHETHER THE SIMPLE AND RAPID SEPHADEX GEL FILTRATION COULD RECOGNISE JAUNDICED NEWBORNS WITH NON ALBUMIN BOUND BILIRUBIN WHICH ARE PRONE TO MANIFEST LATER SIGNS OF BILIRUBIN ENCEPHALOPATHY.

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Quantitative Imaging of Human Hemoglobin Binding to Staphylococcus aureus With Single‐Molecule Resolution

Small, EarlyView.
Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.

Isomaltitol exacerbates neutrophilia but reduces eosinophilia : New insights into the Sephadex model of lung inflammation

, 2010
We have previously examined isomaltitol in an in vitro static adhesion assay between isolated granulocytes and cultured human umbilical cord vein cells and were interested in investigating whether the potentially anti-inflammatory effects observed there ...

Antifungal Activity of an Abundant Thaumatin-Like Protein from Banana against Penicillium expansum, and Its Possible Mechanisms of Action

Molecules, 2018
Thaumatin-like protein from banana (designated BanTLP) has been purified by employing a simple protocol consisting of diethylaminoethyl Sephadex (DEAE–Sephadex) chromatography, gel filtration on Sephadex G50, and reversed-phase chromatography.
