Fluorescence labeling
Multiple labeling
Recommended filter sets (Shaner C. et al)

- Propose cyan,yellow,orange and red => minimal crosstalk
- [http://www.clontech.com/products/detail.asp?product_id=10426&product_group_id=1437&product_family_id=1417&tabno=2 Reef Coral Fluorescent Proteins -Clontech]
- Said to be suitable for multiple labeling but forming tetramers (toxicity)

Biobricks
FPs that are available from the registry in standardized Biobrick-form
Yeast specific:
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_J63001 BBa_J63001], [http://partsregistry.org/wiki/index.php?title=Part:BBa_E2030 BBa_E2030] -enhanced version of EYFP, yeast-optimized YFP
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_E2020 BBa_E2020] -enhanced version of ECFP, yeast-optimized (works?)
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_E2050 BBa_E2050] -derivative of mRFP1, yeast-optimized (works?) => mOrange
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_E2060 BBa_E2060] -derivative of mRFP1, yeast-optimized (works?) => mCherry
Notes:
- Contains N- and C-terminal linker sequences (with homology to biobrick parts BBa_E2060 (mCherry), BBa_E2050 (mOrange), and BBa_E2020 (Cerulean CFP) to facilitate color swapping in yeast.
- Adds N-"MATSG" and "GSGTA"-C. to published amino acid sequence.
- Inserts a "V" after normal start M.
- Double TAATAA stop codon.
- Missing EcoRI, HindIII, NotI, NdeI, XhoI, RsrII, BamHI, NcoI, BglI, SpeI, XbaI, and PstI.
- Except for 5' and 3' ends no significant sequence identity runs with Cerulean CFP (BBa_E2020) or to GFP S65T as found in O'Shea deletion strain collection (originally from plasmid pFA6-GFP(S65T)-His3MX6).
