Synthetic DNA Libraries

Synbio Technologies offers high quality DNA libraries of any size and complexity with an efficient time frame and at industry’s most competitive rate. Our synthetic DNA libraries are designed by an experienced bioinformatics team to facilitate various research applications, including functional genetics, directed evolution, protein engineering and antibody studies.

Why us?


Proprietary synthesis platforms guarantee the successfully synthesis of multiple libraries and reasonable library preparation.


High quality libraries can be accurately synthesized with large capacity (up to 1014 variants), coverage rate>95%, uniformity index<10.


Flexible deliverables: oligo pools, PCR fragments, pooled clones or error-free separated colonies.
