StayGold variants explained!

Posted by Christophe Leterrier, on 19 December 2023

I figured it might be useful as a reference, so here’s a blog-ified version of a thread I posted on X about recently published monomeric variants of the StayGold fluorescent protein. Thanks to Helen Zenner of FocalPlane for the help! In 2022, the Katayama/Miyawaki labs published StayGold, a bright and stable fluorescent protein (FP) from

These proteins were observed first in bioluminescent organisms known to humanity for centuries. We can find examples of light-emitting organisms in multiple taxa: from single cell organisms like bacteria, to vertebrates like fish.
