Build DNA Variant Libraries

Pioneering Synthetic Biology - Sequencing and Combinatorial Libraries

BioXp® error-corrected libraries kits

BioXp error-corrected libraries kits are built using proprietary technology that leverages de novo DNA synthesis, error correction, and amplification. The final product is purified library gene fragments ready for downstream applications such as cloning, screening, or selection.

Through the power of push-button, end-to-end automation of the BioXp system, error-corrected libraries are assembled in a single instrument run of less than 16 hours – regardless of design complexities – enabling researchers to reduce synthesis bottlenecks during Design-Build-Test cycles of lead optimization significantly.

Accelerate your path to discovery.

Library synthesis time is independent of design complexity.

Confidence in your results

DNA with the diversity you need & the fidelity you expect

Solve complex challenges

Escape from the design limitations of service providers.

BioXp error-correction technology

Delivering both fidelity and diversity – from an overnight instrument run

library builds on the BioXp

The impact of error-correction technology on the mean error rate of the library builds on the BioXp.

Sequence fidelity increases approximately 2-fold with error correction than without. Median error rate as measured across a panel of representative standard libraries spanning 300-800bp, GC 30-60%.

Diversity generation analysis of degenerate codons

Generation of diversity is unaffected by error-correction technology. Expected vs. observed amino acid distribution analysis from 32 unique NNK degenerate codons with and without error correction.

Median Error Rate: 1 in 5000 bp

Scanning libraries

BioXp scanning error-corrected libraries offer a wide variety of libraries with varied amino acid sites which can be categorized into simple-scanning (single amino acid/codon substitutions per well) and site-saturation libraries that employ NNN, NNK, and NNS degenerate codons.
