Are there brighter versions of GFP or RFP out there?

Have you ever heard about Superfolded GFP? It is 50% brighter than GFP! And mScarlet is almost 6 times brighter than mRFP! How do I know? I look at this fantastic database called FPBase.

You can see which fluorescent protein is monomeric, sort them by excitation and emission or find which bleaches least or maturates fastest! Great tool! 🙂

Fluorophores are constantly being developed. If you make a new plasmid, make sure you check that the one your lab has been using for trillions of years is the very best one!
