Scientists from Kyoto University designed reagents that labeled proteins only in the presence of zinc ions for later analysis by mass spec.

With executives from Agilent, Thermo Fisher, Waters, and Danaher presenting this week at the JP Morgan Healthcare Conference, UPLC as well as triple quadrupole and qual-quan mass spec proved primary areas of discussion.

The purchase, which is expected to close in the first quarter of 2011, will add a range of ion and liquid chromatography products to Thermo Fisher's portfolio, including platforms aimed at proteomics research like Dionex's UltiMate 3000 RSLCnano LC system.

The company plans to release new columns and mass spec ion source emitters sometime next year to more fully take advantage of the Easy-nLC technology, said an official.
