|Specificity and functionality of microRNA inhibitors|
Barbara Robertson, Andrew Dalby, Jon Karpilow, Anastasia Khvorova, Devin Leake and Annaleen Vermeulen
Our findings indicate that features important for natural miRNA target recognition also appear to be important for inhibitor specificity. Understanding the specificity of inhibitors allows for better interpretation of inhibitor activity in endogenous systems.
|Alternative miRNA design for therapeutic RNAi applications|
Anja van Brabant Smith, Barb Robertson, Annaleen Vermeulen, Christina Yamada, Angela Reynolds, Anastasia Khvorova, Devin Leake
For in vivo applications, the design of miRNA inhibitors and miRNA mimics must be optimized for stability and potency. However, stabilized miRNA mimic molecules can lose functionality compared to standard miRNA mimic molecules due, in part, to the activity of the stabilized passenger strand acting as a miRNA inhibitor. We discuss how mismatches affect the activity of the stabilized miRNA mimics, perhaps by generating a passenger strand that is less functional as an inhibitor molecule.
|Integrating Fluorescent Carbon Nanodot Synthesis and Optical Detection of Methylmercury|
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla
In the last years, a great interest toward development of optical nanoprobes has arisen, so fluorescent nanomaterials have been implemented in analytical systems for the detection of several species. In this work, a novel assay that integrates the synthesis of fluorescent carbon dots (CDs) and sensing within one step, for the fast, sensitive and selective detection of methylmercury is presented.
|Impact of Molecular Surface Charge on Electrical Impedance Spectroscopy Biosensing|
Y. Ram, T. Yoetz-Kopelman, A. Freeman and Y. Shacham-Diamand
Molecular surface charge was found to be the dominant parameter when monitoring protein binding events by Electrical Impedance Spectroscopy with a charged redox couple. A biosensing device was fabricated, and a physical model was derived to explain the results.
|Investigating the Effects of Commercial Antimicrobial Agents on Human Corneal Epithelial Cell Membranes|
Ian J. Horner, Jerod J. Hurst, Nadine D. Kraut, Alyssa A. Rook, Crystal M. Collado, G Ekin-Atilla Gokcumen, and Frank V. Bright
Several commercial multi-purpose solutions (MPS) products contain polyhexamethylene biguanide (PHMB) and/or polyquaternium-1 (PQ-1) as antimicrobial agents. In this poster we report the effects of PHMB and PQ-1 on small unilamellar vesicles (SUV) that we have designed to mimic the average human corneal epithelial cell membrane.
|A multiplexed amplicon sequencing technology for FFPE and circulating, cell-free DNA|
Laurie Kurihara, Catherine Couture, Julie Laliberte, Sukhinder Sandhu, Jonathan Irish, Tim Harkins and Vladimir Makarov
A novel amplicon approach allowing for hundreds of amplicons to be multiplexed in a single tube with a two workflow from sample to sequencer.
|Stable Chloroplast: Myth or Reality?|
Shailesh Joshi and Dyfed Evans
Chloroplasts principally encode the photosynthetic machinery in Viridiplantae. It has long been accepted that in photosynthetic plants chloroplast genomic structure is uniquely stable as it is maternally and clonally inherited. The first chloroplast genomes sequenced supported this view. The current study was undertaken to address the potential issue of global chloroplast(in)stability.
|Validation of Collection and Extraction Methods of Saliva for Use in Biomarker Research|
Sarah E. Hurst and Brandon T. Hall
This poster investigates the collection and extraction methods of saliva for use in biomarker research.
|Rapid Detection of Somatic Mutations in Cancer Genes|
Michael J. Powell et. al.,
Rapid higly sensitive detection of tumor gene mutations in DNA derived from FFPE or plasma samples can be achieved with QClamp PCR technology.
