Cell-free synthesis and amplification of genome-scale large DNA

01 SUMMARY

Cell-free assembly and amplification aimed at replacing cell-based cloning

OriCiro offers ground breaking, cell-free technologies of large DNA assembly and amplification that can effectively replace the conventional E. coli cloning process.

02 ASSEMBLY

Hyper assembly of multiple DNA fragments

  • One-step isothermal reaction, cell-free, easy-to-handle
  • Seamless assembly via overlapping homologous ends (25 - 60 bp)
  • Simultaneous assembly of up to 50 fragments
  • Assembly of large DNA fragments up to 200 kb

03 AMPLIFICATION

In-vitro reconstitution of chromosome replication cycle

  • Whole replication cycle of the E. coli chromosome is reconstituted in vitro using purified proteins.
  • The replication cycle repeats autonomously and continuously allowing to "exponential" amplification of circular DNA.
  • Requirements for the template DNA are "circular configuration" and "oriC sequence (300 bp)."

Cell-free hyper amplification of large DNA

  • One-step isothermal reaction, cell-free, easy-to-handle
  • Up to 100 ng/µl supercoiled DNA produced within 3 hours at 30ºC even from a single DNA molecule (for 10 kbp DNA)
  • Extremely high fidelity
  • Applicable to a wide range of DNA size from 1 kbp to 1 Mbp
  • Applicable to any sequence including GC-rich sequences

04 COMBINATION

Efficient cell-free production of circular DNA from multiple DNA fragments

  • Apply the assembled products directly to the amplification reaction.
  • Circular DNA (complete assembled products) can be amplified selectively from a single molecule level.
  • No need of purification process after assembly as unnecessary intermediates (linear DNA) are not amplified.
