LOCUS       sequence-207906-        6806 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Concomitant expression of two proteins. One protein expressed with 
            Cerulean, cleavable by 3C; second protein expressed with Venus, 
            cleavable by TEV. Useful for protein interaction analysis by FRET..
