In this article, we continue addressing the analysis of ligand-protein interactions by NMR. Now, we will focus on one of the key experiments that monitor the recognition process from the ligand’s viewpoint: 'The Saturation Transfer Difference' method. The employment of this technique permits the existence of interaction and, in favourable cases, the identification of the ligand epitope to be...

Agilent Technologies has produced this 100+ page e-book in which you’ll find tips on how to boost ICP-OES productivity, handle difficult samples, and simplify method development. There’s an overview on how ICP-OES addresses the specific needs of environmental, food and agriculture, energy and chemicals labs – as well as 18 detailed application-specific papers.

For the second article of this series of articles on Raman spectroscopy I will review some of the latest in Raman technology. Raman has become one of the most important technologies. The large number of vendors with Raman spectrometers of different sizes is overwhelming.

PerkinElmer has produced an application note demonstrating the advantages of the NexION 2000 ICP-MS for analysis of trace elements in urine.

Tips on ICP-MS Instrument Maintenance and Troubleshooting To Improve Best Practices

As an ICP-MS user do you need to improve your levels of productivity and efficiency? As a major supplier of spectroscopy and chromatography instruments, supplies and services, Agilent can assist by providing access to the power of its resources, knowledge and expertise.

In the next issues, we will comment on how to set up different experiments to analyse protein-ligand interactions by using NMR spectroscopy. First, we will focus on experiments that monitor the recognition process from the ligand’s viewpoint, starting with the TRNOESY experiment, which allows the conformation of a particular ligand at the receptor’s binding site to be deduced.

The Indian physicist, CV Raman, received the Nobel Prize for his discovery of Raman scattering. Raman found that when monochromatic light from a Hg lamp passed through a solid or liquid sample, such as benzene, a small amount of light was scattered in all directions but at a frequency lower (longer wavelength) than the incident light frequency. We note that a group of Russian scientists...
