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

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!
