Undergraduates

Involvement of undergraduate students in scientific research

Student training includes biosafety, keeping records of laboratory supplies and inventory, animal handling and usage for research, basic microbiological methods, tissue culture, basic molecular biology methods (RNA/DNA isolation, quantitative PCR, gel electrophoresis), immunoassays (ELISA) development, and maintaining data in computers. Successful establishment of standard tissue culture for Chlamydia inoculation and detection methods elevates the capacity for educating and training students in biomedical research. After training, the students become involved in performing experiments.  Several students present posters annually in the WV-INBRE summer research symposium, Research Day at the State Capitol, Annual Biomedical Conference for Minority Students and in the General Meeting of the American Society for Microbiology.
