MetabolomicsPlant elicitor peptide signalling confers rice resistance to piercing-sucking insect herbivores and pathogens
Rice is a staple food crop worldwide, and its production is severely threatened by phloem-feeding insect herbivores, particularly the brown planthopper (BPH, Nilaparvata lugens), and destructive pathogens. Despite the identification of many BPH resistance genes, the molecular basis of rice resistanc...

MetabolomicsMetabolomic Profile of Diet-Induced Obesity Mice in Response to Human and Small Humanin-like Peptide 2 Treatment

INTRODUCTION: The mitochondrial-derived peptides (MDPs) are a novel group of natural occurring peptides that have important signaling functions and biological activity. Both humanin and small-humanin-like peptide 2 (SHLP2) have been reported to act as insulin sensitizers and modu...

ProteomicsTissue protease activity with MALDI MSI
Aberrant protease activity has been implicated in the etiology of various prevalent diseases including neurodegeneration and cancer, in particular metastasis. Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) has recently been established as a key technology for bio...

MetabolomicsThe genetic origin of evolidine, the first cyclopeptide discovered in plants, and related orbitides

Cyclic peptides are reported to have antibacterial, antifungal and other bioactivities. Orbitides are a class of cyclic peptide that are small, head-to-tail cyclized, composed of proteinogenic amino acids, and lack disulfide bonds; they are also known in several genera of the plant family Rutacea...

ProteomicsMALDI Quant Fibrinogen
Absolute quantification of protein was performed by MALDI-LTQ using scramble internal standard (sIS) peptide. Mixtures of serial dilutions of fibrinogen peptides (final concentration: 50, 100, 250, 500 and 1000 fmol/μL), equal amounts of corresponding sIS peptides (final concentration: 500 fmol/μL) ...

ProteomicsElectrospray ionization in concentrated acetonitrile vapor improves the performance of mass spectrometry for proteomic analyses
Suppressing the background interferences and enhancing the analyte signals are long-term goals in high performance electrospray ionization mass spectrometry (ESI-MS) analyses. We observed that performing electrospray in the presence of a concentrated acetonitrile atmosphere suppresses background int...

ProteomicsEnhancement of Tryptic Peptide Signals from Tissue Sections using MALDI IMS Post-ionization (MALDI-2)
Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) allows for highly multiplexed, unlabeled mapping of analytes from tissue sections. However, further work is needed to improve sensitivity and depth of coverage for protein and peptide IMS. Laser-based post-ionization ...

ProteomicsVacuum insulated probe heated electrospray ionization source (VIP-HESI) significantly enhances micro flow rate chromatography signals in the Bruker timsTOF mass spectrometer.
Nano-flow chromatography-tandem mass spectrometer (nLC-MS/MS) is a popular choice in proteome research as it provided high-sensitivity analysis with minimal sample usage, but its quantitative proteomics applications become restricted by low analytical throughput, and low robustness. To circumvent th...
