Presentation Transcript

  1. 2008 Nobel Prize in Chemistry Green fluorescent protein, GFP Marty Chalfie Obtained the GFP gene (gfp) clone from Prasher in 1992. Made promoter::GFP And Promoter::GFP::Gene expression vectors to show the When and where genes are expressed. Osamu Shimomura Jellyfish/ bioluminescence Purified and characterized GFP (1974) Roger Tsien Figured out how GFP glows Made variants with different colors

  2. 2008 Nobel Prize in Chemistry the other guys Sergey A. Lukyanov Identified and cloned GFP-like proteins in corals Douglas Prasher The first person to realize the potential of GFP as a tracer molecule. Cloned GFP in 1992!
