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...

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...

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...

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...

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...

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...

We report methods development for quantitative proteomic analysis of samples with limited number of cells. The improvements include suspension trapping (S-Trap) for sample processing, longer analytical column length (75cm), and a segmented data dependent acquisition approach. The modified approach w...
