[NMR paper] Understanding heme proteins with hyperfine spectroscopy
Understanding heme proteins with hyperfine spectroscopy
Publication date: July 2017
Source:Journal of Magnetic Resonance, Volume 280</br>
Author(s): Sabine Van Doorslaer</br>
Heme proteins are versatile proteins that are involved in a large number of biological processes. Many spectroscopic methods are used to gain insight into the different mechanistic processes governing heme-protein functions. Since many (intermediate) states of heme proteins are paramagnetic, electron paramagnetic resonance (EPR) methods, such as hyperfine spectroscopy, offer unique tools for...

[NMR paper] One-Step Microfluidic Fabrication of Polyelectrolyte Microcapsules in Aqueous Conditions for Protein Release
One-Step Microfluidic Fabrication of Polyelectrolyte Microcapsules in Aqueous Conditions for Protein Release
We report a microfluidic approach for one-step fabrication of polyelectrolyte microcapsules in aqueous conditions. Using two immiscible aqueous polymer solutions, we generate transient water-in-water-in-water double emulsion droplets and use them as templates to fabricate polyelectrolyte microcapsules. The capsule shell is formed by the complexation of oppositely charged polyelectrolytes at the immiscible interface. We find that attractive electrostatic interactions can...

T2 Biosystems gets two more patents for assay
Mass High Tech
In February, the company won another patent (8,102,176) which broadly covers the use of nuclear magnetic resonance to detect analytes. The assay can detect â??anythingâ?? in biological samples, said McDonough, ranging from certain types of DNA to proteins ...

[Question from NMRWiki Q&A forum] NMR integral of Hydrophobically modified polyelectrolyte
NMR integral of Hydrophobically modified polyelectrolyte
Hi there, I have a polyelectrolyte polyethylenimine (PEI) grafted with DSPE-PEG (lipid-polyethylene glycol). I have some problem in calculating the grafting density. I do that by the integral of the two polymers.
It does not dissolve (not a clear solution) in CHCl3, CH2Cl2, MeOH, DMF. OK in water (clear after heating/sonication) and good in DMSO. But the peak of DMSO (2.5) overlap with the peak of PEI (2.4-3.3).
In water, the peak of the lipid is very bad and it is not "right" (coz it is with PEG and the ratios between PEG and...

Biochemistry. 1999 Jun 1;38(22):7219-26
Authors: Xian W, Tang JX, Janmey PA, Braunlin WH
Under physiological conditions, filamentous actin (F-actin) is a polyanionic protein filament. Key features of the behavior of F-actin are shared with other well-characterized polyelectrolytes, in particular, duplex DNA....
