|Characterization of Proteins and Protein Self Association (Oligomerization) with SEC-MALS|
Michel Terray, Mark Pothecary
In this poster, a series of proteins and their oligomers were characterized using SEC-MALS with UV and RI detection. The monomer molecular weights are measured and compared with those from column calibration. The molecular weights of their oligomers are also compared with column calibration and the differences explored.
|Identifying Molecular Signatures of Tumors Using Novel Fluorescence Resonance Energy Transfer Networks|
Vishwa Nellore, Chris Dwyer
We developed FRET sensors that can detect 125 fluorophores simultaneously. From experimental analyses of over 1200 time-resolved fluorescence signatures on 300 prototypical sensors, we show that the optical responses are highly repeatable and minor variations between FRET networks can be discriminated resulting in a total of 10^375 unique responses in theory.
|Amino-Coated Metallofullerene Nanoparticles for Glioblastoma Mutiforme Tumor Detection|
Tinghui Li , Susan. Murphy, Kanwarpal Bakshi, Steven LaConte, Zhi Sheng, and Harry Dorn
We report the preparation of a new functionalized trimetallic nitride endohedral metallofullerene, with a cage surface consisting of positively charged amino groups, which is expected to bind more efficiently to negatively charged cell phospholipid bi-layer cellular surfaces and will more readily undergo endocytosis. We now report that this Gd-nanoplatform when subsequently conjugated with an IL-13 peptide, (IL-13-Gd3N@C80(OH)x(NH2)y) exhibits enhanced targeting of U-251 GBM cell lines.
|Design and Evaluation of High Definition Probe for HPV genotyping Microarray|
Sihn Ae Lee, Ah Reum Park, Inyoung Kim, Ji Hyung Lee, and Jongwon Kim
To improve the sensitivity and specificity of the HPV DNA Microarray, we adopted triple oligonucleotide probes for each targets and selected these probes not to have higher similarity of 75% with each others. These triple probes have shown 10 ~ 100 times higher sensitivities with comparable specificities than the conventional HPV DNA microarray of single oligonuclotide probe.
|Gut Microbial Metabolites and Hepatic Xenobiotic Metabolism: A High Throughput Screening Approach|
Glynn Martin, James Sidaway, Jonathan Swann
This poster highlights the combination of metabonomics and high throughput screening by the identification of gut microbial metabolites and a screening assay designed to determine their cytotoxicity to liver-like cell cultures.
|Digital PCR to Determine the Number of Transcripts from Single Neurons after Patch-clamp Recording|
Nóra Faragó1,2, Ágnes K. Kocsis3, Sándor Lovas3, Gábor Molnár3, Márton Rózsa3, Viktor Szemenyei3, Ágnes Zvara2, Gábor Tamás3, László G Puskás1,2
Whole-cell patch-clamp recording enables detecting electrophysiological signals from neurons, and RNA can be harvested into the patch pipette from the cells.We have optimized a dPCR protocol for determining exact transcript numbers in single neurons after patch-clamp recording by using dPCR based on high-density nanocapillary PCR.
|Rapid Quantification of Proteins in Complex Matrices using the DeNovix DS11 Microvolume Spectrophotometer|
Mebs A Surve & Dan Schieffer
In this poster, we will introduce the DeNovix DS-11 as the next generation in microvolume spectrophotometry.
|Mixtures Analysis of Complex Mixtures|
Michael Bernstein; Carlos Cobas; Santi Domínguez; Manuel Pérez; Agustín Barba
We describe an NMR method to quantify mixture components in wine, edible oils, etc. The method is fully customizable, and amenable to high throughput operation.
|A Complete Wine Analysis Using Multiplets Detection|
Dr Michael Bernstein1; Agustín Barba1; Dr Susanne Klein2; Dr Andrea Dreiseitel2; Daniel Heidger2 and Volker Heidger2
NMR mixtures analysis can be used to determine the concentration of key components in wine. Here we show the analysis using SMA from Mestrelab.
