We report a technique to selectively and continuously label the proteomes of individual cell types in coculture, named cell type–specific labeling using amino acid precursors (CTAP). Through ...

Reactive carbenes provide a nonselective way to label amino acids on the surface of proteins, Canadian biochemists report (Anal. Chem., DOI: 10.1021/ac102655f). The method offers researchers a new ...

Conventional mass spectrometric proteomics methods don’t work well for low-abundance proteins in complex mixtures. Edward M. Marcotte, Eric V. Anslyn, and coworkers at the University of Texas, Austin, ...

For customers who want to do quantification of human protein biomarkers through Mass Spectrometry (MS) analysis, ACROBiosystems now offer a range of heavy-labeled proteins alongside a material ...

Aphids survive on an unbalanced diet of plant sap by breaking down all available plant amino acids and rebuilding essential ones, new research shows. Aphids suck up an almost endless supply of sugary ...

This is a preview. Log in through your library . Abstract In the aquatic liverwort Riccia fluitans, membrane depolarization (Δψm), change in membrane conductance (Δgm), and current-voltage (I-V) ...

In ESR, a spin label is added to the target site using cysteine substitution. This is followed by modifying the sulfhydryl group with a paramagnetic nitroxide reagent. The ESR then provides ...

Aphids suck up an almost endless supply of sugary sap from their plant hosts. They can survive on this junk food diet because bacterial partners help them convert the handful of amino acids in the sap ...
