FAQ: Using amplicons directly without precloning seems much easier, but is the assembly efficiency decreased?

While in general DNA is more stable in circular form than in linear form due to the absence of free ends, amplicons are a viable and easy way to build assemblies as long as they have been purified and stored in 10 mM Tris (pH 8.0), 1 mM EDTA (TE). The suggested 2 fold molar ratio of amplicon inserts:pGGA vector brings the assembly efficiency to that of precloned inserts (using 75 ng of each plasmid) for most assemblies.
