It takes an age: Art pigments influence degradation of protein-based binders under UV light
Date: Apr 15, 2012
Author: Steve Down
The ageing of protein-based binders in works of art by UV light is affected by the presence of pigments, say European scientists, who followed the changes in rabbit glue. The findings should be useful in the fields of restoration and conservation.

Journal Highlight: Towards a universal LC-MS screening procedure - can an LIT LC-MSn screening approach and reference library be used on a quadrupole-LIT hybrid instrument?
Date: Mar 12, 2012
Author:
The aim of the study was to prove whether a recently developed linear ion trap LC-MSn screening approach and reference library can be transferred to an LC-MS/MS system with a quadrupole-LIT hybrid mass analyzer using SmileMS, a sophisticated search algorithm.
