Position description

Under supervision, plan and design experiments, teach other students and lab members, perform experiments, make observations, record experimental data related to research projects, write and author manuscripts for publications, and present data in oral and poster sessions.
Use basic cellular and molecular biological techniques to perform tissue and sterile cell culture, immunologic assays, flow cytometry, cell sorting, ELISA, Western Blotting, and development of plasmid and viral-based gene transfer vectors. Manage animal studies including assisting with breeding, injections, tumor models, and maintaining and screening transgenic mouse colonies. Assist with fluorescent imaging, radiation delivery, necropsy, tissue processing, flow cytometry, cell sorting, and histology. Perform basic laboratory activities in the lab including ordering equipment and reagents, and researching journal articles to find appropriate protocols and regulations for experiments.

Job Functions

a) Assist with experimental techniques in the following areas:

• Tissue/Cell Biology: media preparation, monitoring of equipment necessary to support cell growth, cell culture and replating assays with or without specific inhibitors and cryopreservation of cells, the long term culture assays, immunofluorescence assays, DNA cloning techniques (such as DNA digestion by restriction enzymes, ligation, plasmid transformation in bacteria, DNA purification from cells and from bacteria to construct lentiviral and other vector), transfect human or mammalian tissue culture cells and primary cells, grow and maintain stock tissue culture cell lines using sterile techniques and produce cultures and viral stocks for experiments
• Molecular Biology: Plasmid construction, DNA and RNA handling, PCR, RT- qPCR, and other related molecular biology techniques according to study protocols; isolate nucleic acids or proteins from cells and perform separation by gel electrophoresis and western blotting
• Immunology: ELISA, FACS analysis of human and mouse myeloid, T, B, and NK cells in various tumor models and genetically engineered mice following transplantation. Operation of FACSCalibur machine, LSR II, BD ARIA, and high-speed cell sorters.
• Histology: preparation of samples for microtomy, staining tissues with labeled antibodies specific for cellular antigens
• Animal work: Assist with the writing of animal subject protocols, prepare instruments, generate animal models, Maintain and screen transgenic mouse colonies, drug administrations, prepare animals for surgery, monitor animals during recovery and throughout the length of projects, perform humane euthanization of laboratory animals
• Radiation delivery using fixed source cesium irradiators, x-ray irradiators, as well as small animal irradiators to deliver radiation treatment to cell cultures and murine tumor models.
