Our CT GFP-fusion TOPO® Expression kit provides pcDNA™3.1⁄CT-GFP-TOPO® vector for highly efficient, 5 -minute cloning that fuses the green fluorescent protein (GFP) to the C-terminal end your Taq polymerase-amplified gene product. The pcDNA3.1 vector delivers high-level expression of transient or stable GFP fusion proteins in a wide range of mammalian cells Expression is easily detected in living cells using fluorescence. In addition, recombinant proteins expressed from these vectors can be detected on western blots using GFP Antiserum.
