Immune checkpoint receptors are promising new immunotherapy
targets for the treatment of a variety of diseases including cancer and
autoimmune-mediated disorders. We developed a suite of cell-based
bioluminescent reporter bioassays for individual and combination
immune checkpoint immunotherapy targets including: PD-1 (PD-L1 or PD-L2), CTLA-4, LAG-3, TIGIT, PD-1+TIGIT, GITR, 4-1BB, CD40, and OX40.

Synthetic, dual-RNA-encoded Cas9 is used for precise homology-directed repair (HDR) gene engineering. Both short and long (GFP) inserts are covered.
|Mobility of Aeroallergens in Home: Effect of Location of Air Sampling and Implication for Evaluation of Patient Exposure|
Julian Gordon1, Paul Detjen, Andrea Wachter & Prasanthi Gandhi1
The Inspirotec sampler permitted the easy testing of multiple locations within a household. Air sampling simultaneously at 12 locations by other technologies would have been technically challenging. These were run by an untrained operator.
|Lutjanus jocu (Dog snapper) as a bio-indicator of emerging contaminants and changes in environmental condition.|
M. Sánchez-García1, S. J. Zottoli2 & L.Roberson-Murillo1
Our research assesses the use of Lutjanus jocu as a bioindicator of changes in environmental condition and water contaminated with toxic substances in estuarine ecosystems.
|Determination of C2-C12 Aldehydes in Water by SPME Arrow On-Fiber Derivatization and GC/MS|
Peter Egli, Beat Schilling, Guenter Boehm, Kai Schueler
A method applying SPME Arrow extraction and on-fiber derivatization for the quantitation of C2-C12 aldehydes in water by GC/MS is described.
|Building a digital pathology ecosystem for education and research|
Yves Sucaet, Silke Smeets, Stijn Piessens, Sabrina D'Haese, Chris Groven, Wim Waelput, Peter In't Veld
We wanted to build a core digital pathology infrastructure to support different use cases. Various images platforms needed to be accessible through a single access point, and support different user profiles. We wanted a scalable solution that would allow interaction between equipment from different research groups.
We built a centralized infrastructure that integrates a variety of imaging platforms, and now have an interconnected network of heterogeneous and scalable information silos.
|Minimizing Carry-over for High Throughput Analysis|
Christian Berchtold1, Reto Bolliger2, Guenter Boehm2, Götz Schlotterbeck1
Minimal carry-over is a prerequisite for high throughput analysis. However, minimized carry-over and cycle time are competing and a careful optimization is mandatory. In this study the influence of wash conditions on carry-over of various compounds was investigated. A strategy to minimize carry-over was developed. The influences of different wash tasks were investigated. Finally the contribution of different system components such as injector valve or column was studied.
|A Comparison of ITEX Dynamic Headspace–GC/MS to other Enrichment Techniques for Analysis of Flavoring Compounds|

Enrichment techniques are commonly used for the analysis of flavoring compounds in different matrices with GC/MS. Analysis of flavoring compounds is done by purge & trap, SPME or headspace, depending on requirements for sensitivity. The In-Tube Ex¬traction (ITEX) Dynamic Headspace uses a micro trap filled with an adsorbent material to efficiently extract the compounds. Here we evaluate if the ITEX can be used to effectively analyze for these compounds and reduce the analyst’s time involved.
