Gene Synthesis Compared to Molecular Cloning

The core techniques and tools used in molecular biology have been optimized over many years, but many challenges still remain. Our Molecular Biology Guide can help you through the basic techniques and troubleshooting.  However, these challenges are amplified when the goals are more complex, which is the case with many molecular biology and synthetic biology (engineering) projects. Very often, gene synthesis is a solution to these challenges.

Gene synthesis services by GENEWIZ provide:

  • 2-5 µg lyophilized plasmid containing synthetic DNA construct
  • Optional custom cloning into the vector of your choice
  • Optional scaled-up DNA preparations
  • Certificate of Analysis (C of A), including restriction digest confirmation
  • Sequence trace data with alignment data
