Neurotoxicity Assays Using iPSC-Derived Neurons and High Content Imaging
Oksana Sirenko, Susan DeLaura, Lucas Chase, Jayne Hesley and Evan F. Cromwell

Neurotoxicity can cause temporary or permanent damage of brain or peripheral nervous system and has been found to be a major cause of neurodegenerative diseases such as Alzheimer’s or Parkinson’s. Accordingly, there is a great interest in developing more predictive, disease relevant cell-based models and efficient screening tools for assessing the neurotoxicity of chemical compounds, drug candidates and environmental agents.

SpectraMax® Microplate Readers: A complete solution for Transcreener® assays
Cathleen Salono, Caroline Cardonnel, Kasia Proctor and Cathy Olsen

Transcreener® ADP2 Assays are homogenous assays with fluorescent readouts that enable the detection and screening of established drug targets including protein and lipid kinases, as well as emerging targets such as carbohydrate kinases, triphosphatases, heat shock proteins and other ATPases.

Live Cell Beating Assay Using Human iPSC-derived Cardiomyocytes for Evaluation of Drug Efficacy and Toxicity
Oksana Sirenko, Carole Crittenden, Blake Anson, Jayne Hesley, Yen-Wen Chen, Nick Callamaras and Evan F. Cromwell

A large percentage of new drugs fail in clinical studies due to cardiac toxicity. Development of highly predictive in vitro assays suitable for screening, safety assessment or other environments is therefore extremely important for drug development. Human cardiomyocytes derived from stem cell sources can greatly accelerate the discovery of cardiac drugs and improve drug safety by offering more clinically relevant cell-based models than those presently available.

Identification of novel autoantigensin patients with liver autoimmune diseases by Protein MicroArray
C. Zingaretti1, M. Arigò1, A. Cardaci1, A. Sinisi1, L. Muratori3, P. Colombatto4, F. Bonino2, P. Invernizzi5, , A.L. Zignego6 MC. Crosti1, M. Moro1, J. Geginat1, Pagani M.1, R. De Francesco1, S. Abrignani1. & M. Bombaci1

The characterization of autoimmune disease-specific biomarkers are of primary importance for the development of diagnostic tools and the comprehension of pathogenetic mechanisms leading to autoimmunity. To this aim a protein microarray was employed to analyze serum samples from patients with autoimmune hepatitis (e.g. AIH & PBC) and of healthy as controls. A panel of autoantigens able to discriminate among the groups of patients was identified for potential use as biomarkers.

Attempts of facilitated DelF508-CFTR trafficking to the plasma membrane
Sergey Shityakov, Massimo Micaroni, Alexander A. Mironov, Alberto Luini

Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations of the CF transmembrane conductance regulator protein (CFTR), a cAMP-regulated chloride channel. One of the most common CFTR mutations is the deletion of phenylalanine in 508 position (DelF508-CFTR). This mutation induces small conformational change hence the CFTR trafficking is no more effective. The main idea is to find a molecule to facilitate the DelF508-CFTR trafficking to the plasma membrane.

Production of Naturally Compressed Screening Arrays
Steven A Trim.

Animal venoms and toxins are a rich source of novel biologics with several making the progression from tool to therapeutic such as FDA approved Integrilintm (Eptifibatide) (Millennium pharmaceuticals)1 derived from Rattlesnake venom for unstable angina.

A fast and fully automated solution for Lipidic Cubic Phase (LCP) screening using mosquito LCP
Joby Jenkins1, Patricia Edwards2, Rob Lewis1and Joanne Franklin1

Membrane proteins, such as G-protein-coupled receptors, are known to be much more difficult to purify and crystallise than soluble proteins due to their native environment within the lipid bilayer of the cell membrane. The in meso (lipidic cubic phase or LCP) crystallisation technique has revolutionised the process of crystallising membrane proteins. This method utilises highly viscous lipid mesophases to contain the membrane proteins for crystallisation.

A high-throughput colony formation assay for profiling novel compounds and RNAi reagents using the Acumen® eX3
Andrew Goulter and Jason Mundin

Cell colony formation assays measure a cell's ability to grow unattached to a surface and have applications in a range of areas including hematopoietic stem cell research, cell transformation studies and the prediction of responses of tumors to chemotherapeutic agents. The results of this study demonstrated that Acumen eX3 can be used as a high-throughput platform for investigation of effects of test compounds and RNAi reagents on cell colony formation.

High-throughput imaging of cellular models using an Acumen eX3
Paul Wylie, David Onley

The Acumen eX3 is the fastest imaging system available, collecting and simultaneously analysing over 40 images/second, covering the entire well, without the trade off of having to use lower resolution. Acumen is well established for cell-based high-content screening, but researchers have recently applied its large field of view to rapidly analyse complex cellular or animal models, such as angiogenic tube formation, C. elegans or drosophila larvae.
