Analytical chemistry, 73(8), 1699-1706 (2001-05-08)
The use of triethylammonium bicarbonate (TEAB) solution in electrospray mass spectrometry proved to be a very efficient way for studying proteins or noncovalent protein complexes under "nondenaturing" conditions. The low charge states observed in the mass spectra improve the separation

Autophagy, 16(12), 2180-2192 (2020-01-28)
In plants, macroautophagy/autophagy has mainly been associated with stress-related processes but how it impacts normal physiological and developmental processes remains largely unexplored. Pollen germination is the critical first step toward fertilization in flowering plants. It is metabolically demanding and relies
