Gene Libraries

Gene Libraries

SeSaM-Biotech offers mutant gene libraries as a service provider. Our customers provide us with their gene of interest, we evolve the gene by random mutagenesis technologies, especially by our core technology SeSaM.

After a quality control, the final mutant gene library is returned to the customer within 4 weeks usually.

 

What is SeSaM?

SeSaM, the abbreviation of Sequence Saturation Mutagenesis, is a patented method to create diversity on the gene level far higher than the diversity generated by conventional methods such as error-prone PCR.

Why is SeSaM the ideal random mutagenesis method?
  • SeSaM targets every single protein position equally
  • SeSaM exchanges an amino acid by all the other 19 amino acids with a probability above 0.9
  • SeSaM has a built-in recombination option
  • SeSaM libraries have reduced hotspots that leads to decrease in screening needs
  • SeSaM allows tuning of the Ts/Tv-ratio
