Registry of standard biological parts/PCR-based assembly

• Automated PCR primer design for worm genes - This is a good example of a simple CAD tool to encourage assembly. You could imagine something similar to auto-generate the primers necessary for PCR-based assembly of standard parts.
• Sauer:Stitching Genes by PCR
• patent on some of this stuff

Demo

Going to get a better feel for this by doing a few biobrick constructions using PCR-assembly

• Registry of standard biological parts/PCR-based assembly/Protocol

1. <bbpart>J04500</bbpart>+<bbpart>I13501</bbpart> = <bbpart>J04450</bbpart>
2. <bbpart>R0010</bbpart>+<bbpart>I13504</bbpart> = <bbpart>J04430</bbpart>

1. <bbpart>F2620</bbpart>+<bbpart>P1010</bbpart>+<bbpart>E0240</bbpart>
   • will try this one as a 3-way

UDG

Can use UDG (NEB USER enzyme) to replace all restriction digests and could also eliminate secondary PCRs also. You would just need to design your oligos to contain a U in the right location, assuming that there'll be a T somewhere in the vacinity of the ends of the parts you are trying to combine.

In-Fusion

• Clontech In-Fusion PCR cloning -- this could be used for the last step so that we don't need to do a digest/ligation at any point in the process.
  • Using In-fusion to combine multiple parts
• Seamless cloning and gene fusion review [1]
• Useful forum discussion
• Patents: 1, 2 (might be same as 1, title same though filing date is later), 3
• This reference describes a system similar to In-Fusion using the vaccinia virus DNA polymerase [2]
