April 9, 2019

- Proof-of-Concept Data Presented for GPCR Library and Antibody Optimization Solution –

-- Additional Data Demonstrates Power of Twist Single-Site Variant Libraries and Combinatorial Variant Libraries --

SAN FRANCISCO & BOSTON--(BUSINESS WIRE)--Apr. 9, 2019-- Twist Bioscience Corporation (NASDAQ: TWST), a company enabling customers to succeed through its offering of high-quality synthetic DNA using its silicon platform, today announced the presentation of four posters at PEGS (The Essential Protein Engineering Summit) highlighting proof-of-concept data validating its GPCR library, antibody optimization solution to improve antibody therapeutics, and the drug discovery applicability of two types of synthetic variant libraries.

“Taken together, these data illustrate the robust power of precisely-defined synthetic libraries to explore all relevant variations for screening antibody therapeutics,” said Emily M. Leproust, Ph.D., CEO and co-founder of Twist Bioscience. “As we continue to forward integrate, we are now able to offer our customers exceptionally high quality synthetic libraries for their internal discovery efforts and now we have proof-of-concept data for our biologics discovery platform that demonstrate the value of our GPCR library as well as our antibody optimization solution approaches.”

All posters were presented on Monday, April 8, 2019.

Poster Number: A103

Precision Synthesis of Variant Libraries Enables Comprehensive Interrogation of Single Site Variant Space

The data presented demonstrate that Twist Bioscience’s massively parallel DNA synthesis platform, combined with advanced molecular biology technologies for library construction, creates more uniform and precise variant libraries than any other method for comprehensive generation and evaluation of functional and non-functional diversity for protein engineering.

Poster Number: A104

A High-Throughput Platform to Develop Highly Potent and Functional Antibodies Against G-Protein Coupled Receptors

The proof-of-concept data demonstrated that our high-throughput antibody discovery platform identifies functional antibodies against GPCR targets within a few months, and can readily develop antibodies with affinities in the nanomolar range. These antibodies exhibited many modes of action to modulate GPCR activity.

Twist Bioscience's Silicon-Based DNA Synthesis Platform Enables the Construction of Focused Variant Libraries with Unprecedented Precision

The data demonstrate that combinatorial variant libraries are powerful tools that accelerate the exploration of the large variant space in antibody engineering, pathway engineering, and protein engineering. The poster highlights Twist Bioscience’s ability to construct complex high-diversity libraries at confined regions (i.e. CDRs), and introduce technology advancements to enable the construction of synthetic DNA libraries with diversity scattered along the length of the construct to home in on the target of interest.

Poster Number: A106

Rapid Optimization and Humanization of an Anti-PD1 Antibody

The proof-of-concept data showed that our antibody optimization software successfully generated antibodies with similar or improved binding affinity when compared to commercial PD-1 antibodies Keytruda and Opdivo.
