Access to Expertise

Our years of molecular biology expertise combined with the Twist DNA Synthesis Silicon platform ensures that you receive the exact library you want with no compromises.

Complex Custom Libraries

Twist’s proprietary oligo synthesis technology offers a unique approach to library creation. The silicon-based synthesis platform generates high-quality oligo pools, which are used to build fully-customized, user-defined variant libraries on a single chip. Twist's unparalleled platform also enables the creation of thousands to billions of specific variants. You can be assured exactly what you design is exactly what you get.

High Diversity Variant Domains

Twist has developed high fidelity methods for precisely splicing large pools of oligonucleotides (with composition and length variation) to create NGS verified combinatorial diversity of up to 10^10 unique variants within a single domain. Every variant is designed in-silico and screened prior to synthesis, eliminating unwanted sequence bias, premature stop codons, and undesirable motifs.

What Scientists Have to Say

The Library we’ve asked for was very complex. Based on our analysis, the library we received was excellent. What we’ve designed is what we’ve obtained.

Dr. Sandrine Moutel

Manager of Technology • Institut Curie Recombinant Antibody Platform and TAb-IP Platform

Working with Twist was a great experience. Twist’s support was amazing. We have performed the first validation selections which looks promising.

Dr. Ahuva Nissim

Professor in Antibody and Therapeutic Engineering • Queen Mary University of London

We have performed the first selections using the Fab and scFv libraries. No problem in both cases, we got clones and some look really promising.
