Open protocol for Ligase Independent Cloning
You can look up Gibson Assembly or Circular Polymerase Extension cloning (CPEC).  For both of these the website for J5 has some good protocols.  Here is the one for CPEC:  http://j5.jbei.org/j5manual/pages/80.html

For CPEC you can look at the 2011 Quan paper: http://www.ncbi.nlm.nih.gov/pubmed/21293463

Hopefully that helps.
