3. A recent report shows that a novel cytokine (STC) can increase the abundance of stem cells in mice's bone marrow. Boss K thinks that purified human STC can be injected into donors prior to bone marrow harvest. Worker P managed to express lots of STC in E. Coli and STC is soluble in E. Coli extract. Boss K wants Worker P to make a polyclonal antibody in rabbits and then use the antibody to purify STC in a large quantity for clinical trial.

Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.
