Cytotoxicity Screen of Mangiferin and its Major Metabolite Norathyriol in Human Tumor Cell Lines
Souza, J.R.R., Feitosa, J.P.A., Ricardo, N.M.P.S, Trevisan, M.T.S., Frei, E., Ulrich C.M., Owen, R.W.

Many natural products are available worldwide as potential chemoprotective agents against commonly occurring cancers, for example Mangiferin which has low bioavailability and is thought to be mainly available in the colon.

Effect of Liquid Handling Quality Control on Biological Assay Performance
Nathaniel Hentz, Ph.D and Tanya Knaide

High quality assays are required in order to take forward potential drugs, post screening. Therefore the liquid handling must be accurate and precise, as demonstrated in this experiment.

Why Is My Assay Failing? An Approach to Assay Equipment Optimization
Tanya R. Knaide, John Thomas Bradshaw, Kevin Khovananth, Keith Albert

Assays can produce unexpected or failing results for a multitude of reasons. Variability may be introduced at any point within the assay process.

An Automated, Cell-based Platform for the Rapid Detection of Novel Androgen Receptor Modulators
Brad Larson, Bruce Sherf (INDIGO Biosciences), and Peter Banks

The Androgen Receptor (AR) is a member of the family of nuclear receptors responsive to steroid hormones. This poster aims to devise, validate and perform a preliminary automated HTS screening campaign to identify novel modulators of AR activity.

Automated Solutions for Cellular Screening and Characterization of Therapeutic Antibodies for Antibody-Dependent Cellular Cytotoxicity Utility
Brad Larson, Peter Banks , Nicolas Pierre, Stéphane Martinez, and Francois Degorce

Since the end of the 1990’s, the pharmaceutical industry has seen an increased interest in biologics, especially in the therapeutic areas of oncology and inflammation. Here we present the automation of two assays for the characterization and selection of potent antibody drug candidates. Both assays rely on HTRF® detection. The first assay quantifies the binding affinity of antibodies to their target antigen, on live cells.

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.
