Duties

Cincinnati Children's Hospital Medical Center in Cincinnati, Ohio seeks Research Assistant IV to conduct independent and directed scientific studies and research in support of a Principal Investigator's research relating to the isolation of immune cells from inflamed tissues and preparation of nuclei for multiome analysis. Design and perform experiments and record data. Follow and formulate existing protocols as well as develop, verify, standardize, and establish new published procedures. Independently reproduce, evaluate, research, and improve techniques currently used in the lab such as DNA, RNA, and protein extractions, western blotting and mammalian cell culture. Perform lentiviral transduction experiments and select cells with successful transduction and integration. Isolate and stimulate immune cells and optimize subsequent molecular protocols to be used to assess these cells. Analyze data, perform statistical and graphical analysis of data, and interpret flow cytometry results from stimulated immune cells. Prepare libraries for assay for transposase-accessible chromatin using sequencing (ATAC-seq) and chromatin immunoprecipitation sequencing (ChIP-seq) and pool libraries for sequencing. Maintain accurate and detailed records of all laboratory work and experiments relating to immune cells. Modify existing procedures as necessary to troubleshoot or make modifications based on changes in research design. Maintain protocol and assay accuracy by conducting regular quality and reproducibility checks. Maintain inventory of laboratory supplies and equipment, and operate laboratory apparatus and equipment for isolation of immune cells from inflamed tissues and preparation of nuclei for multiome analysis. Communicate with team members and contribute to their growth by sharing knowledge, experience, and skills. Assist in training postdoctoral fellows, graduate students, and junior laboratory personnel in laboratory techniques and equipment. Contribute and write material for reports, publications, journal articles, and abstracts and maintain an integral role in the laboratory's meetings, presentations, and publications.
