When the measured beta - galactosidase activity in the pWP - transfected cells was normalized to the pCH110 - transfected cells ( an appropriate control if the SV40 early region promoter functions constitutively in various cell lines ) , the results suggested that the promoter region of the PLP gene contains the information necessary for initiation of transcription in a C6 cell - specific manner .
 GENE: beta - galactosidase; GENE: SV40 early region promoter; GENE: PLP gene
