Validation of an Automated Cell-Based Bioluminescent TNFa Blocker Bioassay
Brad Larson, Tracy Worzella, Rich Moravec, Neal Cosby, Frank Fan, Teresa Surowy and Peter Banks

TNFa blocker biopharmaceuticals represent an important and successful class of protein drugs used in the treatment of several autoimmune diseases. Bioassays are indispensible tools in biopharmaceutical drug development and commercialization that are used to quantify biological activity and stability of drugs or drug candidates. The automation of these assays can serve to create an accurate, robust process which can allow the researcher to perform other more important functions.

Automation of a Generic Fluorescence Methyltransferase Activity Assay
X. Amouretti, P. Brescia, P. Banks, G. Prescott, Meera Kumar

Epigenetic processes are attracting considerable attention in drug discovery as their fundamental roles in controlling normal cell development and contributions to disease states become more clearly defined. This work combines a fluorescence-based assay with liquid handling and dispensing instrumentation and a multi-mode reader which can be used to monitor the biological activity of the histone methyltransferase (HMT) G9a, a model system.

Automation of a Novel Cell-Based ELISA for Cell Signaling Pathway Analysis
Wendy Goodrich, Peter Banks, Ron Osmond, Antony Sheehan

Monitoring and quantifying cell signaling pathways is critical for understanding the behavior of cell processes and many disease states. Monitoring and quantifying cell signaling pathways is critical for understanding the behavior of cell processes and many disease states.

Efficacy of Using a Combination Microplate Washer for Vacuum-Based DNA Sequencing Reaction Cleanup
Wendy Goodrich, Jason Greene, Mary Louise Shane

The ability to determine the specific pattern of base pairs in DNA molecules is an indispensable part of contemporary molecular biology. This poster demonstrates how the vacuum filtration module available on the BioTek 405 Touch effectively cleans contaminating artifacts from DNA sequencing reactions, which wil contribute to the genomic workflow typical of many molecular biology laboratories and core facilities.

Improving Cell-Mediated Cytotoxicity Assessment through the Use of an Automated Luminescent ADCC Assay
Brad Larson, Sumant Dhawan, Shalini Wadwani, and Peter Banks

Assays that can assess the ability of a biosimilar to act in a manner similar to the original biologic have seen increased interest. This poster describes the use of a non-radioactive luminescent chemistry to simplify the assay process and provide improved data quality.

Antigen Determination in Autoimmune Hepatitis Type1
Naveen L Gupta, S Nayak, S Shakeyavar

Objectives of this project were to exploit the database in indian setting to determine nuclear antigens as target for antinuclear antibodies (ANA) in patients of autoimmune hapatitis (AIH) type1.

High Content Analysis of Neural Stem Cell Expansion and Differentiation
Oksana Sirenko, Allan C. Powe, Steven L. Stice, Karen Cook, Nick Callamaras, Jayne Hesley, Xin Jiang and Evan F. Cromwell

Automated assay methods for monitoring neural stem cell expansion and differentiation using stem cell derived neural cell lines and high content imaging systems have been described.

Global Gene Expression Changes Induced In Primary Human Hepatocytes By Thiazolidinediones Upon Repeat Dosing of HepatoPac™ Cultures
Michael McVay and Salman R. Khetani

An assessment of global gene expression changes in HepatoPac, a micropatterned co-culture of hepatocytes and stromal cells.

High-Throughput Campaign to Identify Reversible Small Molecule Inhibitors of p97
Kelin Li, Tsui-Fen Chou, Kevin Frankowski, Brian E. Nordinc, Patrick Porubsky, Mathew P. Patricellic, Han-Jie Zhou, Sam Gerritz, Raymond J. Deshaies, Jeffrey Aubé, Frank J. Schoenen*

The AAA ATPase p97 is a critical factor in maintaining protein homeostasis in eukaryotic cells. Two probe compounds ML240 and ML241 were developed that both inhibit p97 ATPase activity with an IC50 of approximately 100 nM, and block degradation of p97-dependent proteasome substrate with an IC50 of approximately 900 nM and 3500 nM, respectively. They specifically targeted p97, exhibited markedly different potencies for activating executioner caspases and blocking cell growth.
