Isolation, Identification, and Determination of Designer Anabolic Steroids Commonly Found in Dietary Supplements
Sarah E. Voelker, M.S.; Travis M. Falconer, Ph.D.; Jonathan J. Litzau; Mary B. Jones; Lisa M. Lorenz

A general analytical approach in identifying emerging steroid-like compounds is presented, including analysis by GC-MS, LC-MS, and/or HPLC-UV. Isolation of unknown compounds was achieved by high performance liquid chromatography with fraction collection. Isolated compounds were characterized by Nuclear Magnetic Resonance spectroscopy and high resolution accurate mass-mass spectrometry to elucidate their structure.

Combining low and high volume liquid handling capabilities for ADME screening
Joby Jenkins, Kevin Moore, Stephen Fowler, Pascal Schenk

In this study we demonstrate the integration of two liquid handlers to extend the volume dispensing range creating low-volume assay-ready plates with high accuracy and precision. This was then successfully applied to a CYP inhibition assay.

Colony Forming Cell (CFC) Assays Predict for Increased Clinical Neutrophenia with Combination Therapies
Dos Santos G, Mergaert A and Clarke E.

This study aimed to assess if the CFC assay could also be useful at predicting the increased toxicity of drug combinations relative to the toxicity caused by the relevant single agent.

High-Throughput Analysis of DNA Samples using the D1K ScreenTape Assay and the Agilent 2200 TapeStation System
Arunkumar Padmanaban, Ruediger Salowsky, Adam Inche

Recent advances in genomics demands to look at a wealth of genetic information in a short period of time. DNA analysis using slab gel electrophoresis and capillary electrophoresis are widely being used as a QC step in next generation sequencing and microarray studies. However, often these techniques lack the speed and involve more manual steps to perform the assay.

An In Silico Test Battery for Rapid Evaluation of Genotoxic and Carcinogenic Potential of Chemicals
Kiril Lanevskij, Liutauras Juska, Justas Dapkunas, Andrius Sazonovas, Pranas Japertas and Remigijus Didziapetris, of ACD/Labs and Vilnius University

The FDA guidance for industry states impurities under the ICH threshold may be exaluated for genotoxicity and carcinogenicity. This study uses an expert system to detect mutagens and compounds labeled as potent carcinogens by the FDA.
