产品介绍:pFRT/lacZeo is a 8106 bp vector that expresses a fusion protein containing β-galactosidase and the Zeocinô resistance marker under the control of the SV40 early promoter.Note that neither the lacZ gene nor the Zeocinô resistance gene contains its native ATG initiation codon. The ATG initiation codon is placed directly upstream of a FRT site and allows expression of the lacZ-Zeocinô fusion gene in cells.
