GenBuilder™ DNA Assembly
GenScript's GenBuilder™ DNA Assembly technology takes recombination-based cloning to the next level. Pushing the bounds of innovation, the GenBuilder™ technology allows for seamless fusion of one to twelve gene fragments with the highest efficiency. Whether using fragments longer than 5 kb, unpurified PCR products, single stranded DNA inserts, or have only fifteen minutes to complete the cloning reaction- the GenBuilder™ DNA Assembly technology helps you build your constructs quickly and accurately.

GenBuilder™ FAQs
- I routinely receive 400ng of GenParts™ fragment. Is this sufficient for the GenBuilder™ cloning?
For a 1 kb fragment, 400 ng GenParts™ fragment is generally sufficient for about six GenBuilder™ reactions. - Should the GenParts™ fragment be gel-purified or spun-purified prior to using it in the GenBuilder™ reaction?
All GenParts™ fragments are gel-purified before shipping, so no additional purification is required before using them with the GenBuilder™ cloning kti. - What is the minimum required overlap length for DNA assembly with GenBuilder?
A 40 bp overlap is optimum for obtaining the maximum cloning efficiency. For cloning one or two fragments into a construct, a 15 bp overlap may be sufficient. For larger number of fragments, we recommend using a 40 bp overlap to increase cloning efficiency. Please see experiment 4.1 (pages 5-6) to see data for cloning together 2 fragments with different over>lap lengths. - When using ssDNA as a bridge, how long can the ssDNA be (not including the overlap site)?
We have tested 20 bp ssDNA inserts without issues. For longer ssDNA fragments, the acceptable insert length may have to be determined experimentally.
| How GenBuilder™ DNA Assembly works |
|---|
1. Prepare the DNA fragments with overlaps and the linearized vector for assembly.  2. Add DNA fragments and linearized vectors in the GenBuilder™ master mix. Mix well and incubate at 50°C for 15 minutes.  3. Transform assembly product into competent cells and plate on selective medium. Obtain colonies containing the assembled DNA.  |
GenBuilder™ Kit features
