Enhancing Protein Engineering: Site Saturation Variant Libraries

Scientists compared protein engineering with a synthetic library versus error-prone PCR to achieve better variant representation and simpler validation.

Share

Site Saturation Variant Libraries (SSVLs) are synthetic libraries for protein engineering. SSVLs are designed alternatives to libraries generated by random error-prone PCR (epPCR), a conventional technique that suffers from amplification bias, incomplete variant representation, and premature stop codons. Scientists use SSVLs to overcome the limitations of epPCR for protein engineering and directed evolution experiments.
