Dual reporter genes driven by either a ubiquitous cytomegalovirus (CMV) or a neuro-specific tubulin α1 promoter (Tα1) were constructed. The new genes, CMV (pCMV-GL) or Tα1 promoter-driven GFP-LacZ (pTα1-GL), robustly expressed the fused GFP-LacZ protein reporting constitutive expressions in various cell types including CHO cells, loach and chicken embryos, and neuro-specific expression in differentiating mouse embryonic stem cells, respectively. The dual reporter genes thus provide a versatile tool for the studies of gene expression, cell lineage within the embryo and possibly the fate of stem cells in transplantation experiment, thus facilitating different analyses depending on the experimental purposes.
