This poster demonstrates the automation of a 96-well homogeneous bioluminescent TNFα blocker bioassay based on quantification of caspase 3 activity. The bioassay can be performed in a single day, and uses single-use, frozen U937 (human) cells which exhibit rapid response to TNFα. A simple, yet robust liquid handler was used to automate the assay steps of antibody titration and of cell and reagent dispensing.
We utilized paired synthetic crRNAs coupled with our synthetic tracrRNA in cells transduced with lentiviral Cas9 to perform a functional knockout on hsa-miR-221. This three-part system (crRNA, tracrRNA and Cas9) has demonstrated efficient gene editing when used with only one guide RNA, but the goal was to use two crRNAs to remove the entire stem-loop.READ MORE
Schistosomiasis is associated with poverty, a lack of clean water and sanitation and is is transmitted through snail vector. Remote sensing methodologies were used to identify types of vegetation that are significantly associated with snail presence as previous studies had shown that removal of certain aquatic vegetation decreased the prevalence of schistosomiasis in nearby villages.READ MORE
