isobaric tagging

At the National Center for Quantitative Biology of Complex Systems, scientists hope mass spec will drive new biological questions and vice versa.

Writing in MCP, the researchers provided a survey of techniques for biologists interested in using multiplexed quantitative proteomics in their research.

The reagents, which use combinations of reporter ions, could allow for multiplexes of up to 28 samples, more than double the capacity of existing tags.

A team of Roche researchers has developed a five-plex SILAC method for quantifying the dynamics of tyrosine phosphorylation.

Proteome Sciences said this week that it has signed an agreement with Thermo Fisher Scientific providing access to patents related to its Tandem Mass Tags isobaric tagging reagents in exchange for cash and a no-cost lease from Thermo Fisher for mass spectrometry equipment.

Researchers from the University of Wisconsin-Madison have characterized the mitochondrial acetylome, finding significant changes in protein acetylation in response to calorie restriction and activity of the protein deacetylase SIRT3.

Jay Shendure and his colleagues have developed a new method to more comprehensively identify human cell types, the NY Times reports.

Researchers in the UK and Japan have shown that infertility in mice with three sex chromosomes can be overcome, according to the Guardian.

China is embracing preimplantation genetic diagnosis, Nature News reports.
