The Vivid Colors™ pcDNA™6.2 Fluorescent Protein TOPO™ Expression Vectors (Figure 1) allow you to rapidly clone your gene and fuse it to the widely used and well characterized Fluorescent Proteins (FPs) from the jellyfish Aequorea victoria (1, 2). These powerful TOPO™ cloning vectors contain the Emerald Green Fluorescent Protein (EmGFP) or the Yellow Fluorescent Protein (YFP) for simple, non-invasive detection of recombinant protein (Figure 2). Both FPs have been humanized for optimal mammalian expression (3). The Vivid Colors™ pcDNA™6.2 Fluorescent Protein TOPO™ Expression Vectors offer:
• Topoisomerase I for one-step, 5-minute TOPO™ cloning of your PCR-amplified gene of interest
• CMV promoter for high-level expression of the recombinant fluorescent fusion protein
• Ability to fuse EmGFP or YFP to the N- or C-terminus of your protein
• Bsd resistance marker for rapid selection of stable cell lines
For Research Use Only. Not for use in diagnostic procedures.

Contents & Storage
Each pcDNA™6.2-TOPO™ Expression Vector Kit contains two boxes. The TOPO™ box contains linearized and topoisomerase I-activated pcDNA™6.2-TOPO™ vector, control template, primers for sequencing, PCR reaction components, and an expression control plasmid. The TOPO™ box should be stored at -20°C. The One Shot™ box contains transformation reagents including single-use 50 μl aliquots of One Shot™ TOP10 chemically competent E. coli, S.O.C. medium, and pUC19 supercoiled plasmid control. Store competent E. coli at -80°C. All reagents are guaranteed stable for 6 months when properly stored.

Frequently asked questions (FAQs)

Your Gateway-adapted TOPO vectors are supplied with a control template and control primers. Can I obtain the sequence of the control template?

The sequence of the control template is proprietary.

Can GFP fluorescence be detected in cells that have been stained for beta-galactosidase?

We recommend looking for GFP fluorescence before staining for beta-galactosidase. This is because the beta-galactosidase staining process produces a very high autofluorescence that will interfere with detection of GFP fluorescence.

What are the recommended filter sets for detection of EmGFP, YFP, CFP, and BFP by fluorescence microscopy?

EmGFP, YFP, CFP, and BFP can be detected using standard FITC filter sets and settings. However, for optimal detection of the fluorescence signal, filter sets optimized for detection within the excitation and emission ranges for each fluorescent protein are recommended. The recommended filter sets are as follows: EmGFP: Omega filter set XF100 YFP: Omega filter set XF1042 Chroma filter set 41028 CFP: Omega filter set XF114 Chroma filter set 31044 BFP: Omega filter set XF10 Chroma filter set 31021 For information on obtaining filter sets, please contact Omega Optical, Inc. (www.omegafilters.com) or Chroma Technology Corporation (www.chroma.com) directly.

What are the excitation and emission maxima for your fluorescent proteins (EmGFP, YFP, BFP, CFP, and Cycle 3 GFP)?

Excitation and emission maxima for our fluorescent proteins are as follows:
- EmGFP: Excitation: 487 nm; Emission: 509 nm
- YFP: Excitation: 514 nm; Emission: 527 nm
- BFP: Excitation: 308-383 nm; Emission: 440-447 nm
- CFP: Excitation: 452 nm; Emission: 505 nm
- Cycle 3 GFP: Primary excitation: 395 nm; Secondary Excitation: 478 nm; Emission: 507 nm

Are the fluorescent proteins you offer (EmGFP, YFP, CFP, BFP, and Cycle 3 GFP) humanized?

Yes, all of the fluorescent proteins offered by us (EmGFP, YFP, CFP, BFP, and Cycle 3 GFP) have been humanized for optimal mammalian expression.
