Invitrogen's™ pLenti6.3⁄V5™-TOPO™Cloning Kit is part of our ViraPower™ HiPerform™ Lentiviral Expression System (catalog K5310-00).

The pLenti6.3⁄V5™-TOPO™ -TA Cloning Kit contains the TOPO™- adapted ViraPower™ HiPerform™ lentiviral expression vector, pLenti6.3⁄V5™-TOPO™ for quick PCR-based cloning and high-level expression of a target gene in dividing and non-dividing mammalian cells. The pLenti6.3⁄V5™-TOPO™ vector is equipped with two key genetic elements, making it a HiPerform™ vector: the Woodchuck Posttranscriptional Regulatory Element (WPRE) and the central Polypurine Tract (cPPT) sequence from the HIV-1 integrase gene to produce at least 4-fold increase in protein expression compared to vectors lacking these elements.

Advantages
• Stable expression
• Long-term experiments
• Accurate titer of functional virus
• 5 minute, high-efficiency TOPO™ PCR cloning in three simple steps

Key Features
• HiPerform™ WPRE and cPPT elements
• CMV promoter
• V5 epitope tag at C terminus
• Blasticidin selection

Kit includes
• A lacZ vector as a positive control, pLenti6.3⁄V5-GW⁄lacZ™
• Stbl3™ competent cells

Frequently asked questions (FAQs)

Can I store my competent E. coli in liquid nitrogen?

We do not recommend storing competent E. coli strains in liquid nitrogen as the extreme temperature can be harmful to the cells. Also, the plastic storage vials are not intended to withstand the extreme temperature and may crack or break.

How should I store my competent E. coli?

We recommend storing our competent E. coli strains at -80°C. Storage at warmer temperatures, even for a brief period of time, will significantly decrease transformation efficiency.

What is the best molar ratio of PCR product:vector to use for TOPO TA cloning? Is there an equation to calculate the quantity to use?

We suggest starting with a molar ratio of 1:1 (insert:vector), with a range of 0.5:1 to 2:1. The quantity used in a TOPO cloning reaction is typically 5-10 ng of a 2 kb PCR product.

Equation:

length of insert (bp)/length of vector (bp) x ng of vector = ng of insert needed for 1:1 (insert:vector ratio)

What is the best ratio of insert:vector to use for cloning? Is there an equation to calculate this?

The optimal ratio is 1:1 insert to vector. Optimization can be done using a ratio of 0.5-2 molecules of insert for every molecule of the vector.

Equation:

length of insert (bp)/length of vector (bp) x ng of vector = ng of insert needed for 1:1 insert:vector ratio

Does Platinum Taq DNA Polymerase High Fidelity enzyme mix leave 3' A-overhangs on the PCR product for subsequent cloning into a TOPO TA or original TA vector?

Yes, the enzyme mix leaves 3' A-overhangs on a portion of the PCR products. However, the cloning efficiency is greatly decreased compared to that obtained with Taq polymerase alone. It is recommended to add 3' A-overhangs to the product for TA cloning.
