|ROS-Glo™ H2O2 Assay: A Luminescent Assay for Detection of Reactive Oxygen Species Poster|
Gediminas Vidugiris, Sarah Duellman, John Shultz, Jolanta Vidugiriene, Hui Wang, Jean Osterman, Wenhui Zhou, Poncho Meisenheimer and James J. Cali
H2O2 is a reactive oxygen species (ROS) that is measured in cells as a marker of oxidative stress. It is also measured as a marker of enzyme activities that either consume or produce H2O2. It is desirable to screen chemical compounds for their capacity to alter H2O2 levels in cultured cells or for their effects on H2O2 levels in enzyme reactions.

The CRISPR-Cas9 system has the potential to significantly advance basic and applied research.
|Scaffold design, function and over-expression of lentiviral-based microRNAs|
Angela Schoolmeesters, Melissa L. Kelley, Annaleen Vermeulen, Anja Smith, *Mayya Shveygert, *Xin Zhou, *Robert Blelloch Dharmacon, now part of GE Healthcare, 2650 Crescent Drive, Suite #100, Lafayette, CO 80026, USA
Here we describe the strategy for scaffold design, the importance of an optimal promoter, and demonstrate gene target down-regulation from the over-expression of lentiviral microRNA mimics.
|Homology-directed repair with Dharmacon™ Edit-R™ CRISPR-Cas9 and single-stranded DNA oligos|
John A. Schiel, Eldon T. Chou, Maren Mayer, Emily M. Anderson , and Anja van Brabant Smith | Dharmacon, now part of GE Healthcare, 2650 Crescent Drive, Suite #100, Lafayette, CO 80026, US
Here we demonstrate how to perform lipid based transfections for homology directed repair using DharmaFECT Duo, CRISPR-Cas9 reagents and, synthetic DNA donor oligos.
|Tools for studying and using small RNAs: from pathways to functions to therapies|
Kenneth Chang and Gregory J. Hannon
This poster provides an overview of the tools that have been developed to understand the functions of small RNAs and, conversely, the use of small RNAs as tools. Tools that are based on small RNAs have been exploited to investigate gene function in cultured cells and in living animals. Small RNA biogenesis, discovery and functional roles are explored in detail. Screening approaches to functional genomics, in vivo methods and potential therapeutic applications are discussed.

Melissa L. Kelley, Žaklina Strezoska, Elena Maksimova, Hidevaldo Machado, Emily M. Anderson, Maren Mayer, Annaleen Vermeulen, Shawn McClelland, Anja van Brabant Smith
Overview of various CRISPR-Cas9 reagents to provide the highest efficiency of gene editing in your experiments.
|Knockdown of p53 by Accell self-delivering siRNA causes inhibition of p53-dependent DNA damage response in IMR-32 neuroblastoma cell line and β-amyloid toxicity in rat cortical neurons |
Žaklina Strezoska, Tamara Seredenina1, Devin Leake, Annaleen Vermeulen
Here we describe how application of Accell siRNA enabled the development of a high content screening assay in IMR-32 neuroblastoma cells and a whole culture cell viability assay in primary rat cortical neurons.
|High Performance Comprehensive Two-Dimensional Gas Chromatography Coupled with a High Resolution Multi-Reflecting TOFMS for Confident Non-Target Analyte Identification|
Scott J. Pugh, Viatcheslav Artaev, Mark F. Merrick, Jack Cochran
The use of comprehensive two-dimensional gas chromatography to help increase chromatographic resolution is a major step in tackling the problem of confident peak identification in a complex sample matrix. Combining the separation power of two-dimensional gas chromatography, with resolving power greater than 25,000, and sub ppm mass accuracies of a high resolution multi-reflecting TOFMS is the ideal solution to confident compound identification within a complex sample matrix.
|An Efficient Method for the Incorporation of Molecular Probes at Multiple/Specific sites in RNA: Levulinyl Protection for 2'-ACE ® , 5'-Silyl Oligoribonucleotide Synthesis|
Xiaoqin Cheng, Shawn Begay, Randy Rauen, Kelly Grimsley, Kaizhang He, Michael Delaney
A unique method that uses a levulinate ester as a protecting group to introduce conjugates or molecular probes to virtually any location in a synthetic RNA molecule is discussed. The Levulinyl protecting group is stable in RNA synthesis conditions and can be removed without affecting the other parts of the synthesized RNA. We show the capabilities of this approach with three high-complexity synthesis examples.
