Multiple Sclerosis (MS) is an immune-mediated chronic inflammatory disease affecting the central nervous system. The cause of MS is not known and the mechanism of IFN-beta, a disease-modifying treatment (DMT) approved for MS, is not well-understood. Oligonucleotide microarrays were used to study gen...
L-Lactylation is a recently discovered post-translational modification occurring on histone lysine residues to regulate gene expression. However, the substrate scope of lactylation, especially that in non-histone proteins, remains unknown, largely due to the limitations of current methods for analyz...
Quantitative analysis of the sequence determinants of transcription and translation regulation is of special relevance for systems and synthetic biology applications. Here, we developed a novel generic approach for the fast and efficient analysis of these determinants in vivo. ELM-seq (expression le...
Proteomics workflows have traditionally been divided into discovery-based and targeted approaches, with instrumentation optimized for each. Discovery experiments typically utilize high-resolution analyzers such as the Orbitrap™, while targeted workflows rely on the sensitivity and specificity of tri...
Ribosome biogenesis is pivotal in the self-replication of life. In Escherichia coli, three ribosomal RNAs and 54 ribosomal proteins are synthesized and subjected to cooperative hierarchical assembly facilitated by numerous accessory factors. Realizing ribosome biogenesis in vitro is a critical miles...
A popular method for peptide quantification relies on isobaric labeling such as tandem mass tags (TMT) which enables multiplexed proteome analyses. Quantification is achieved by reporter ions generated by fragmentation in a tandem mass spectrometer. However, with higher degrees of multiplexing, the ...
In this study we sought to examine the characteristics of the reporter ion signal obtained using current generation OT-based MS hardware. We initially focus on re-analysis of a previous experiment where TMT was using in combination with OT-MS3 to study protein expression diversity between histotypes...
