A cancer drug exploration Secrets of the Rainforest A cancer drug exploration

The Mysterious Green Florescent Leaves Hi, I am Tisha While Hiking through the Andean Rain Forest, You and a friend, Tisha, obtain medicinal green leaves from Ramon You bring back to Biotex, a biotech company working on a cure for cancer

Green Florescent Protein Biotex scientists determine that the leaves contain a florescent green protein DNA from the leaves is inserted into bacterial cells

Cloning the Gene from Mysterious Leaves

More on Cloning the Gene…

Purifying the GFP Biotex technicians need to separate the GFP from other bacterial proteins Column Chromatography separates contaminating proteins from GFP The result is a purified GFP that can be tested for its ability to cure stomach cancer

Testing and Placebos GFP will need to be tested on rats before it is allowed for a human trial The US Food and Drug Administration will examine Biotex’s experiments to determine if the protein is safe and cures stomach cancer without negative side effects

Ethics and Economics Once GFP is approved by the FDA, you will develop GFP as a commercial product You will need to be aware of the following viewpoints: FDA, social conscience, patient advocacy groups, and the employees of Biotex You must resolve the dilemmas in order to successfully market GFP

Final Presentations Turn in all lab work with analysis questions Video Presentation of your marketing of GFP Address issues of all dilemmas 1-8

Background Continued…Lesson 6 Protein Chromatography- Hydrophobic Interaction Chromatography (HIC) GFP is hydrophobic and will stick to hydrophobic beads in salt water buffer When salt is removed, GFP will then be collected 4 buffers: 1) Equilibration buffer (salt buffer) 2) Binding Buffer (high salt) Wash buffer (medium salt) Elution buffer (low salt)
