Phage display complements other antibody discovery methods, and offers several benefits for tackling challenging targets. The synthetic nature and the diversity of each Twist library (up to 10 billion variants) enable the rapid identification of antibodies against challenging targets that would otherwise fail due to toxicity or lack of immunogenicity. The recombinant format enables easier genetic engineering and maximizes in vitro manufacturing ensuring batch-to-batch reproducibility and scalability from bench to bedside.
"Twist’s phage library complements our leading recombinant antibody discovery capabilities, adding further scale and diversity and increasing the likelihood of identifying antibodies with the desired properties against emerging or established targets. The partnership supports Abcam and Twist’s commitment to deliver antibodies that have the potential to accelerate the development of innovative research tools, diagnostics and therapeutics."
Alejandra Solache, Ph.D
SVP R&D at Abcam
Under the terms of the agreement, Twist Bioscience grants Abcam the right to engage in research and development activities using Twist single domain (VHH) synthetic antibody library. Abcam has the option to nominate, license and commercialize antibody sequences for diagnostic and research use, in return for license fees and commercial milestone payments. Twist retains the rights to the same sequences for therapeutic application.
"This partnership is an important milestone in Twist’s journey as it allows us to access the research and diagnostic market through Abcam’s commitment to advance discovery, development and commercialization of the resulting antibodies. In addition, this agreement lays the foundations for a long term collaboration with Abcam to drive new commercial opportunities. Importantly, because Twist retains the rights to develop the sequences for therapeutic uses, this partnership has the potential to benefit our internal pipeline as well."

(1) VHH Antibody Libraries
Antibodies contain two variable domains, the heavy and the light chains. A VHH antibody, also known as a nanobody or single domain antibody, is the antigen binding domain of the heavy chain, with three complementary determining regions (CDRs), or areas where antigens bind to the antibody. Twist’s VHH library uses novel methods that combine synthetic and natural approaches to maximize diversity in the 10 billion antibody library, creating high quality VHH libraries for use against any protein target. The small size of the VHH antibodies allow them to access targets that traditional antibodies cannot, with tight binding affinity.
