LOCUS       sequence-235103-        4733 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  We have developed a variant of eGFP, SiriusGFP, that shows over a 
            two fold increase in photostability with utility in methods 
            requiring sustained or high intensity excitation as in 4D confocal 
            or SIM..
