Non-viral ORF cDNA expression plasmids, validated for expression of the indicated gene by tag-specific antibody staining and sequencing. CMV drives expression of ORF cDNA fused to an N- or C-terminal epitope tag, and a downstream fluorescent reporter (GFP or RFP), separated from the cDNA by a 2A sequence. The plasmids were made with optimized vectors for high expression in mammalian cells and are supplied as transfection-ready DNA. Constitutive STAT3ab can be used as a positive control for STAT3 activity in some cells, as a positive control for our STAT3 Reporter Lentivirus. The ORF cDNA codes for the constitutively transcriptionally active STAT3 a/b heterodimer.
