CRISPR-Cas9 genome editing utilizing chemically synthesized RNA
Kaizhang He, Eldon Chou, Amanda Haas, Žaklina Strezoska, Melissa L. Kelley, and Anja van Brabant Smith Dharmacon, part of GE Healthcare, 2650 Crescent Drive, Lafayette, CO 80026, USA

CRISPR-Cas9 gene editing using synthetic crRNA:tracrRNA or sgRNA is highly efficient and easy to use. Synthetic crRNA:tracrRNA is uniquely suited to in vitro and in vivo applications, in particular, DNA-free approach with Cas9 mRNA. Chemical synthesis of guide RNAs allows accurate and rapid production of arrayed crRNA libraries for high-confidence, loss-of-function screens.

Deep Phenotyping - Harnessing Data Richness for Unsupervised High-Content Analysis
Huang Dong, Wang Yi, Maciej Hermanowicz, Ke Yiping, Maja Choma, Lee Kee Khoon, Frederic Bard

Recognising the key challenges, we develop an end-to-end computational framework for HCA dubbed “Deep Phenotyping” that perform unsupervised analysis to leverage on the data richness for the discovery of unknown sub-phenotypes with minimal labeling cost.

Assessment of the Anti-angiogenic Effect of VEGFR2 siRNA in Clonetics™ HUVEC using the Lonza 4D-Nucleofector™ System
Srinivasan Kokatam1 , Kanchan Tiwari1 , Jenny Schroeder2 , Andrea Toell2 , Lubna Hussain3, Preeti Kapoor1

In the current study we have used siRNA targeting VEGFR2 as an example to study knockdown of VEGFR2 and subsequent inhibition of tube formation by HUVECs on Growth Factor Reduced Matrigel™ in a 96-well plate format. The same strategy can be used for screening and validating siRNA based inhibitors of the angiogenic process in vitro and thus could be of utility in anti-cancer screening strategies.

The Case for CASE: Computer-Assisted Structure Elucidation
ACD/Labs

Modern CASE systems such as Structure Elucidator Suite provide the necessary capability accurately elucidate a novel chemical structure for complex molecules based on readily available NMR data sets. This allows organizations to avoid expensive, labor-intensive, and time-consuming synthetic efforts.

Targeting Acute Pancreatitis by Small Molecule Inhibitors of Cyclophilin D
M. Awais, E. Shore, R. Gibson, N. Kershaw, D. Latawiec, S. Pandalaneni, M.A. Javed, L. Wen, D.N. Criddle, N. Berry, L-Y. Lian, P. O’Neill, R. Sutton

Cyclophilin D (CypD) promotes opening of the mitochondrial permeability transition pore, a major contributor to acute pancreatitis. We are developing small molecule inhibitors of CypD as a possible treatment for AP and other conditions where the MPTP plays a role.

Rapid electrochemical impedance spectroscopy for protein detection in Lab-on-a-Chip devices
T. Pardy(a); N. Sleptsuk(a); M. Min(a); J. Ojarand(a); T. Lakspere(a,b); K. Palm(b)

We present results in rapid solution impedance spectroscopy to detect protein interactions (antibody-antigen) in human serum. Two different serum-antibody mixtures are measured in cuvettes, interfaced with screen-printed electrodes to determine whether the experimental setup can detect differences in composition.

Advanced Microfluidic Mixing Device for the Study of Macromolecule Dynamics
Shubha Jain, F. Azam, Dr. H. N. Unni

We have developed and characterized a micro-fluidic mixer to study the macro-molecule dynamics such as kinetics of protein folding, DNA sequencing, single molecule study and detection etc. on a micro-second timescale. Numerical simulation has been performed to analyse the study of mixing performance of micro-fluidics channel.

Analysis of Terpenes Using Gas Chromatography with Vacuum Ultraviolet
Changling Qiu, Jonathan Smuts, Phillip Walsh, and Kevin A. Schug

The VUV absorption spectra for different terpenes were distinctive and differentiable. GC-VUV demonstrated the capabilities for qualitative and quantitative analysis of terpenes in turpertine mixtures. Chromatographic coeluting signals can be deconvolved by the VUV data analysis software.
