Region-specific glycan maps were obtained with ∼120 N-glycan compositions in each region, revealing significant differences in “brain-type” glycans involving high mannose, bisecting, and core and antenna fucosylated species. Additionally, the cell membrane N-glycome of three functional regions of...
Metabolomics is a post-genomic research tool to improve and monitor crop status.In-depth metabolite profiling of oil palm spear leaf, a diagnostic organ.GC and LC/MS characterization based on MSI level.3 amines, 20 amino acids and 6 organic acids were identified with confidence....
通过田间试验样品检测得到的精甲霜灵的消解动态方程,其在黄瓜中半衰期为11.5 d,在土壤中半衰期为13.9 d.精甲霜灵在样品中最低检测浓度为0.02 mg/kg,最小检出量为4 × 1011 g.This work examined metalaxyl-M residue in cucumber and soil using acetonitrile extraction, amino extraction column purification, ...
inTable 1. The errors between the measured and predicted masses were within less than 6 ppm, which demonstrated the high mass accuracy of the instrument. The chromatograms of MEQ and metabolites are shown inFigure 2, and the fragmentation ions and potential neutral losses are shown inFigure 3...
