LOCUS       sequence-105728-        6503 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Shuttle vector compatible with Flp-mediated (Flp-in) transgene 
            integration that allows for conditional Luciferase expression upon 
            integration. The vector contains an FRT site and two mutant loxP 
            sites.
