Mobility of Aeroallergens in Home: Effect of Location of Air Sampling and Implication for Evaluation of Patient Exposure
Julian Gordon1, Paul Detjen, Andrea Wachter & Prasanthi Gandhi1

The Inspirotec sampler permitted the easy testing of multiple locations within a household. Air sampling simultaneously at 12 locations by other technologies would have been technically challenging. These were run by an untrained operator.

Selective Debenzylation of N-Benzyloxypyrazinones in Flow

Selective and reproducible debenzylation of benzyloxypyrazinones by using catalytic transfer hydrogenation in flow chemistry to yield N-hydroxypyrazinones. The flow methodology enabled us to avoid overreduction of the compounds to pyrazin-2(1H)-ones.

A New Dual Luciferase Assay Using NanoLuc® Enables a Second Generation Coincidence Reporter System to Reduce False Hits in HTS Poster
Christopher Eggers, Samuel Hasson, Brock Binkowski, Matt Robers, James Unch, Braeden Butler, , Keith Wood, James Inglese and Frank Fan

Luciferase-based reporter-gene assays remain a cornerstone of high-throughput screening of compounds because of their high sensitivity and dynamic range. However, a substantial number of non-relevant hits can be generated due to direct interaction of compounds with the luciferase reporter.

CellTiter-Glo® 2.0: A Novel Luminescent Cell Viability Assay with Greatly Enhanced Storage Stability
Michael P. Valley, James Unch, Poncho L. Meisenheimer, James J. Cali, and Dan F. Lazar

Here we report on the attributes of a novel ATP detection reagent for cell viability with all of the assay performance of the previous CellTiter-Glo® Reagent, but now with markedly enhanced stability as a single component in a liquid format. These new features provide for much greater ease-of-use in that storage of the reagent at 4°C eliminates the requirement for reagent thawing and minimizes temperature equilibration time.

Design and Validation of Bioluminescent Assays for 3D Cell Culture Models Poster
Terry L. Riss, Michael P. Valley, Chad A. Zimprich, Andrew L. Niles, Kevin R. Kupcho and Dan F. Lazar

Cells cultured in 3D model systems often acquire relatively large in vivo-like structures compared to the thickness of a 2D monolayer of cells grown on standard plastic plates.

iPSC-Derived Cardiomyocytes and Luciferase Reporters: A Robust Reporting Platform for Monitoring Cardioprotection and Pathway Biology in Endogenous Human Tissue Cells
Fiene, S., Thompson, A., Niles, A., Robers, M., Anson, B.

Pathophysiological conditions, medical interventions, and off-target toxicities can all result in cellular oxidative stress. In cardiac myocytes, prolonged and/or excessive oxidative stress can lead to cardiotoxicity: a primary cause of developmental delays, black-box warnings, and post-launch withdrawal of pharmaceuticals.

Testing a Novel Real Time Cell Viability Assay
Amy Landreman, Sarah Duellman, Wenhui Zhou, Jolanta Vidugiriene, Brad Hook

Recently developed assay technologies make it possible to use multi-well plate readers to measure the number of live or dead cells in culture in real time over a period of days. Live cells are measured in real time by adding a reagent containing a shrimp-derived luciferase and a pro-substrate directly to the culture medium. Only viable cells can convert the pro-substrate into a luciferase substrate and generate light.

The P450-Glo™ CYP2B6 Assay: a Rapid and Selective Assay for Measuring CYP2B6 Induction and Inhibition
Dongping Ma, Hui Wang, Poncho Meisenheimer, James J. Cali

We have developed a luminogenic CYP2B6 assay for biochemical CYP2B6 inhibition and for cell-based CYP2B6 induction studies. Here we present the CYP2B6 luminogenic assay characterization and demonstrate its utility for measuring time dependent CYP2B6 inhibition, and for measuring CYP2B6 induction in cultured primary human hepatocytes with normalization to viable cell count.
