When 2D is not enough, go for an extra dimension.

The use of an extra SDS separation in a different buffer system provide a technique for deconvoluting 2D gel spots made of several proteins (Colignon et al. Proteomics, 2013, 13, 2077-2082). This technique keeps the quantitative analysis of the protein amounts and combines it with a strongly improved identification process by mass spectrometry, removing identification ambiguities in most cases....

The Paris Declaration Does Not Go Far Enough

Neurons go toward the light

for continuous transmitter release. This requires a lasting supply of synaptic vesicles. A new article by David Lenzi, William Roberts (University of Oregon, Eugene, Oregon), and colleagues suggests that the SB is a source of these vesicles. The distribution of vesicles on the SB changes sharply in response to stimulation, as seen in electron tomography maps of inhibited versus strongly stimula...
