|Sample Stabilization and Purification Devices for Superior Forensic DNA Storage, Purification and Profiling|
Geoffrey Routh,& Bassam El-Fahmawi
The tools used for evidentiary sample collection are often challenged in criminal cases. Maintaining the integrity of evidentiary samples continues to be a major challenge - especially when samples stay in transit during transportation where sample integrity is highly compromised. Thus, there is a crucial need for a cost-effective, efficient DNA collection and storage system that maintain sample integrity from collection until processing, while providing a means to ensure proper chain of custody
|Development of a nucleic acid-based amplification test as point-of-care rapid test detecting sexually-transmitted diseases for home-care|
Vicky Tröger, Anja Scherber, Dirk Kuhlmeier, Indrek Tulp, Marko Lehes, Steffen Howitz, Toni Bohatzsch, Tamas Pardy
The main problem of early diagnosis of STI is the lack of suitable systems. Therefore a quick home test is needed. In this poster, a microfluidic cartridge combining an isothermal amplification with detection on a lateral flow strip is presented.
|Design considerations for highly specific and efficient synthetic crRNA molecules|
Anja van Brabant Smith, Emily M. Anderson, Shawn McClelland, Elena Maksimova, Tyler Reed, Steve Lenger, Žaklina Strezoska, Hidevaldo Machado Dharmacon, part of GE Healthcare, 2650 Crescent Drive, Suite #100, Lafayette, CO 80026, US
An overview of our rational design algorithm for picking highly functional crRNA sequences in combination with comprehensive specificity analysis.
|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.
|A Novel Bioluminescent HTS Method for Rapid NAD(P)/NAD(P)H Detection Poster|
Jolanta Vidugiriene, Donna Leippe, Mary Sobol, Wenhui Zhou, Gediminas Vidugiris, Troy Good, Laurent Bernad, Poncho Meisenheimer and James J. Cali
Nicotinamide adenine dinucleotides (NAD+, NADH, NADP+ and NADPH) are fundamental co-factors of cellular energy metabolism. These dinucleotides are essential for macromolecule biosynthesis and the maintenance of the cellular redox potential. Our new rapid, easy-to-use assays for measuring dinucleotides are convenient tool for investigating their role in these processes.
|A Simple Plate Based Assay Using pH Sensor Dye to Screen for Internalizing Antibody|
Nidhi Nath, Becky Godat, Cesear Corona, Chad Zimprich, Mark McDougall, Poncho Meisenheimer, Marjeta Urh
Receptor mediated internalization is a key mechanism of action (MOA) for antibody drug conjugates (ADCs). However, current methods of studying antibody internalization have several limitations including: 1) A multistep process not suitable for screening; 2) Low signal-to-background ratios; 3) Not suitable for kinetic measurements. We have developed a method that mitigates problems associated with traditional internalization assays.
|An IgG Cleaving Protease from S equi with Improved Activity Against Mouse IgGs|
Chris Hosfield, Philip Compton, Luca Fornelli, Paul Thomas, Neil L. Kelleher, Michael Rosenblatt & Marjeta Urh
Here we have expressed and purified a modified recombinant IdeZ, and show that it has significantly improved activity against mouse IgG2a and IgG3 subclasses when compared to IdeS. We also demonstrate the use of IdeZ in LC-MS workflows for human and mouse IgG characterization.
|Better Cell-Based Assays for Anti-CTLA-4, Anti-PD-1/PD-L1, and Bispecific Immunotherapy Drug Studies|
Richard Somberg, Mei Cong, Pete Stecha, Natasha Karassina, Jim Hartnett, Zhi-Jie Jey Cheng, and Frank Fan
Here we report the development of a panel of robust reporter assays to measure the potencies for biologics in immunotherapy. These assays reflect mode of action and can serve as valuable tools in immunotherapy drug development and discovery.
|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.
