Supplementary Note

Vectors are available upon request by non-commercial users. GFP 1–10 and GFP 11 can also be prepared by primer-directed mutation of GFPs on commercially available plasmids or by ordering coding sequences from gene synthesis companies.

The GFP 11 cassette can be amplified from pTET plasmid using 0421007 and 02129811 primers. The restriction sites for cloning insert proteins is indicated in bold in the DNA sequence. A frameshift stuffer with three translational stops (one in each frame) prevents false positives from a self-religated plasmid. A 6His tag followed by a thrombin cleavage site is located at the N terminus. The initiator methionine is indicated in bold in the amino-acid sequence of both GFP 11 and GFP 1-10 cassettes. The GFP 1-10 cassette can be amplified using 01079936 and 02129811 primers.
