Session 1850, Room 300
Norman Dovichi, of the University of Notre Dame (South Bend, Indiana) will be presiding over this Wednesday afternoon session.
Following opening remarks by Dovichi, Penny R. Gardner, Immediate Former President of The Pittsburgh Conference, will proceed with the presentation of the 2012 Ralph N. Adams Award to Jonathan V. Sweedler, of the University of Illinois at Urbana-Champaign (Champaign, Illinois).
Sweedler will follow with a presentation of “Neurometabolomics: The Cell-by-Cell Chemical Characterizations of the Brain,” in which a suite of bioanalytical approaches are described that allow the investigation of individual neurons and small brain regions. These approaches include capillary-scale separations coupled to mass spectrometric detection, and direct mass spectrometric-based profiling and imaging.
Paul Bohn, of the University of Notre Dame (Notre Dame, Indiana), will follow with “Spatial Heterocorrelation of Confocal Raman Scattering with Secondary Ion and Laser Desorption-Ionization Mass Spectrometry,” which explores the potential of heterocorrelated mass spectrometric and confocal Raman microscopy chemical imaging, as targeted to the problem of microbial, and environmental processes.
The next presentation in the session is titled “Top Down Proteomics on a High Throughput Basis: Driving Towards High Coverage of the Endogenous Proteome” and will be delivered by Neil L. Kelleher, of Northwestern University (New York, New York). Kelleher will discuss a platform developed in his laboratory for the large scale use of multiplexed 2D separations coupled to capillary LC–LTQ–FTMS to achieve unprecedented proteome coverage.
Following a 15-minute recess, Michael L. Hein, of the University of Arizona (Tucson, Arizona), will present at talk titled “Thin Film Sensors for Zeptomole Analysis of Neurotransmitters.” Hein will describe a novel platform that encompasses thin-film–based sensors to allow for optical microscopy and electrochemical detection from single cells and individual vesicles.
Norman J. Dovichi, of the University of Notre Dame, will give the final presentation, “Diagonal Capillary Electrophoresis,” which offers a universal method to map the phosphorylation pattern of peptides. The method employs two-dimensional capillary electrophoresis with identical separation modes in each capillary.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Metabolomics Analysis of Low Birth-Weight Infants Using UHPLC-MS/MS Following Lipid Emulsion
January 10th 2025A recent study aimed to directly compare the changes in serum metabolites among very low birth-rate (VLBW) infants following the administration of the soybean oil-based lipid emulsion and soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) lipid emulsion using untargeted metabolomics techniques.
Analyzing New Drug Modalities: An ISC 2024 Interview with Kelly Zhang
January 10th 2025At ISC 2024 in Liverpool, United Kingdom, LCGC International interviewed Kelly Zhang of Genentech about her work analyzing new drug modalities, such as mRNA, oligonucleotides, peptides, and cell and gene therapies.
