The pGL4.26[luc2/minP/Hygro] Vector(a–e) encodes the luciferase reporter gene luc2 (Photinus pyralis) and is
designed for high expression and reduced anomalous transcription. The vector contains a multiple cloning region for insertion
of a response element of interest upstream of a minimal promoter and the luc2 gene. luc2 is a synthetically-derived
luciferase sequence with humanized codon optimization. The vector backbone contains an ampicillin resistance gene to
allow selection in E. coli and a mammalian selectable marker for hygromycin resistance.
