StayGold, a newly discoverd green fluorescent protein

StayGold, a green fluorescent protein (GFP) , fluoresces in expression. StayGold has an order of magnitude more photostability than any currently available fluorescent protein. Commonly used to label and trace cellular components. BBa_K4335002 is our StayGold gene optimized for the codon of Chlamydomonas reinhardtii.

Additional Materials

StayGold was extracted from Cytaeis uchidae by Atsushi Miyawaki et al. by the RIKEN Center for Brain Science Research on April 25, 2022.

Absorption spectrum and emission spectrum of StayGold.[Image origin]

StayGold and other 15 kinds of fluorescent protein fluorescence intensity changes with time

StayGold has an order of magnitude more light stability than any currently available fluorescent protein and has a cell brightness similar to that of mNeonGreen. Compared with the 15 fluorescent proteins, StayGold showed good photostability.

Usage

We introduced the StayGold gene into the pTX2040 plasmid. PCrRBCS2 is used as the promoter and TCrRBCS2 is used as the terminator to achieve the expression of the StayGold gene.

Result

We designed two primers: Staygold-F and Staygold-R, and confirmed the successful assembly by PCR amplification.
