|Validation of a 3-Dimensional Human Liver Microtissue Model for Long-term Hepatotoxicity Studies|
Brad Larson1, Stewart Hunt2, Timothy Moeller3, Diana Long4, and Peter Banks1
Non-steroidal anti-inflammatory drugs (NSAIDs) are a class of drug commonly used as analgesics and antipyretics, as well as for management of rheumatological disorders. They are one of the most highly prescribed drug families around the world, and consequently, along with antimicrobial agents, are the most frequent causes of druginduced liver injury (DILI) (Bjornsson et al., 2010).
|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.

|Side by Side: An Evaluation of 2D vs. 3D Cell Culture for High Throughput Screening in Drug Discovery|
Sophie Quick 1,2, Sinead Knight 1, Jon Winter 3
•3D cell culture has the potential to provide a more physiologically relevant model compared to standard tissue culture plastic.
•From a screening perspective the technology offers the possibility of more predictive drug responses but has an increased cost.
•The question: is it possible and, more importantly, is it worthwhile moving towards screening in High Throughput using a 3D model?
|High Throughput Screening in the European Lead Factory|
S.P. van Helden, W.H. Rutjes, C.A.A. van Boeckel and J.H.M. van den Broek
This paper describes workflows that have been implemented at the screening centre of the European Lead Factory and presents screening statistics on the first 18 months of operation.
|Use of a Microlitre Digital Liquid Handler for Screening Applications|
Joby Jenkins, Gillian Lewis, Wayne Bowen
Digital dispensing offers researchers the most freedom for experimental design and sample placement with each microplate. It makes it relatively simple to plan and execute the most desirable experimental design and not one predicated by manual or automated liquid handling.
|Progressing 3D Spheroid Analysis into a HTS Drug Discovery Method|
