  • Design and implement cell-based functional assays using cell lines, reporter cell lines, and primary cells
  • Organizing and analyzing results, troubleshooting assays, communicating and presenting findings in team meetings, and contributing to scientific publications
  • Troubleshooting and optimizing assays through surveying the literature, data interpretation, identification of novel or alternative procedures and techniques, and timely execution of experiments

  • Experience with aseptic cell culture techniques, including cell line growth and primary cell isolation from human or mouse tissue samples
  • Experience with immunological techniques (e.g ELISA/MSD, flow cytometry) and with immune cell based functional assays
  • Experience with at least 4 color flow cytometry and FlowJo software is desirable
  • Gene expression (RT-PCR) and protein expression (immunoblot) analysis is desirable
