ProteomicsA Suspension Trapping-based Sample Preparation Workflow for Sensitive Plant Phosphoproteomics
Plant phosphoproteomics reveals a global view of phosphorylation-mediated signaling in plants, but it remains demanding a high-throughput method with detection sensitivity and quantification accuracy. In general, the indispensable protein precipitation step requiring for interferences removal limite...

ProteomicsSuspension trapping (S-trap) is compatible with typical protein extraction buffers and detergents for bottom up proteomics
Analysis of cells and tissue by bottom up proteomics starts with lysis, followed by in-solution digestion. Lysis buffers commonly used include detergents and other reagents for efficient solubility of the proteins. However these reagents are, for the most part, incompatible with downstream analytica...

ProteomicsAn Optimized Suspension Trapping (S-Trap) Method for Phosphoproteomics Sample Preparation
The performance of the S-Trap protocol for phosphoproteomics studies for proteome and phosphoproteome was systematically evaluated in big-scale and small-scale samples. The results showed the existing protocol was problematic for phsophopeptides enrichment. After employing optimized S-Trap methodol...

ProteomicsSuspension TRAPping filter (sTRAP) sample preparation for quantitative proteomics in the low µg input range using a plasmid DNA micro-spin column: analysis of the hippocampus from the 5xFAD Alzheimer’s Disease mouse model
Suspension TRAPping filter (sTRAP) is an attractive sample preparation method for proteomics study. Here, we demonstrated the use of a low-cost Plasmid DNA spin column for sTRAP. We first evaluated, the reproducibility of this protocol and the low CoV using 4 replicates of 5-10 µg of a synapse enric...

ProteomicsAn ultrafast, reliable and economical approach for quantitative salivary proteomic profiling and oral cancer biomarker discovery
Clinical biomarkers identified by shotgun proteomics require proteins in body fluids or tissues to be enzymatically digested before being separated and sequenced by Liquid Chromatography-tandem Mass Spectrometry (LC-MS/MS). How well peptide signals can be resolved and detected is largely dependent o...

ProteomicsDeceptive Ceropegia sandersonii uses an arabinogalactan for trapping its fly pollinators
Many plant species have evolved surfaces designed to reduce insect attachment. Among such plants are deceptive trap flowers of Ceropegia. Their gliding zones consist of epidermal cells each topped by a papilla secreting a single small liquid droplet on its tip. So far, the molecular and physical mec...

ProteomicsS-Trap is an ultrafast sample preparation approach for shotgun proteomics
The success of shotgun proteomic analysis depends largely on how samples are prepared. Current approaches such as gel-, solution- or filter-based, although being extensively employed in the field, are time-consuming and less effective with respect to the repetitive sample processing, recovery, and o...

ProteomicsTranylcypromine specificity for monoamine oxidase is limited by promiscuous protein labelling and lysosomal trapping
Monoamine oxidases MAOA and MAOB catalyze important cellular functions such as the deamination of neurotransmitters. Correspondingly, MAO inhibitors are used for the treatment of severe neuropsychiatric disorders such as depression. A commonly prescribed drug against refractory depression is tranylc...
