GFP GFPmut3 (Part No: BBa_E0040): Half-life > 1 day (the length of the experiment). It was still expressed after 192 hours. Time to expression = 8 min (this may or may not be the same for other variants of GFP).

This is the common GFP that is in most projects.

BBa_J52028: Half-life = 2 hours. Shorter half-life because an extra piece was added to the protein called Pest that causes it to degrade faster. Others: Other types of GFP have been engineered to last between 40 minutes to many hours. Other types of GFP taken from a paper (which may or may not be on iGEM):

Skim this paper to find out about a bunch of other GFP variants that have specific degradation rates.

  • Note

To find parts, the way that worked so far for me was to go here: http://parts.mit.edu/r/parts/partsdb/search.cgi and search for “gfp.” It will come up with TONS of results but you can sift through them and find what you’re looking for.
