ProteomicsProteomic characterisation of oat grain compartments
In this study, we performed matrix-assisted laser desorption and ionisation mass spectrometry imaging (MALDI-MSI) to map metabolite distributions across oat grain tissues and delineate major compartments of metabolite localisation. These metabolite-rich regions, notably the bran, endosperm and embry...

ProteomicsEgg White as a quality control in MALDI Mass Spectrometry Imaging
Tryptic peptides and N-glycans were spatially mapped and visualised on formalin-fixed paraffin-embedded (FFPE) endometrial cancer tissue microarrays (TMAs) using an ultrafleXtreme MALDI-ToF/ToF MS instrument (Bruker Daltonics). FFPE egg white was placed either side of each TMA and used as an externa...

ProteomicsIEF fractionation OVCAR-5 cell line
Analysis of the ovarian cancer cell line OVCAR-5. A standard trypsin digest was carried out on the OVCAR-5 cell lysates which were then analysed in the un-fractionated and fractionated forms. Fractionation was completed using a peptide IEF separation method. All samples were analysed by nano-LC-ESI-...

ProteomicsIn-house packed porous graphitic carbon columns for liquid chromatography-mass spectrometry analysis of N-glycans
Although many reversed and normal stationary phases have been utilised for the separation of N-glycans, porous graphitic carbon (PGC) chromatography has become desirable because of its higher resolving capability, but is difficult to implement in a robust and reproducible manner. Herein, we demonstr...

ProteomicsT cell activation decreases microRNA-15a/16 levels as a mechanism to promote MEK1-ERK1/2-Elk1 signaling for optimal proliferative capacity
While microRNAs (miRs) have been extensively studied in the context of malignancy and tumor progression, their functions in regulating T cell activation are less clear. We found reduced levels of miR-15a/16 at 3-18 h post-T cell receptor (TCR) stimulation, suggesting a role in shaping T cell activat...

ProteomicsAltered N-linked Glycosylation in Endometrial Cancer
It has been recognised for a long time that cell surface glycans plays a vital role in the biological process and their altered form can lead to cancer. However, the molecular details and regulatory mechanism between the glycans and cancer is yet not clear. Over the past decade mass spectrometry-bas...

ProteomicsDevelopment of an optimized LC-MS workflow for Host Cell Protein characterization to support upstream process development
Host cell proteins (HCPs) co-expressed during the production of biotherapeutics can affect the safety, efficacy and stability of the final product. As such, monitoring HCPs populations and amounts throughout the production and purification process are an essential part of the overall quality control...
