Abii
Technology

The Abii Platform

Three technical innovations working together to deliver sequence-defined, format-flexible recombinant antibodies.

How Abii Antibodies Work

Traditional antibody production treats each product as unique. Abii treats the binder as a permanent asset and the constant region as a configurable parameter.

01

Sequence-Defined Production

Every antibody is produced from a propietary genetic platform. No hybridoma or animal-derived step. The identity of each antibody is fixed at the DNA level, same construct, same antibody, batch after batch.

Expression in industry relevant environments
02

Modular Constant Region

Abii's constructs separate the variable domains from the constant region. Changing the Fc changes which secondary antibody will detect it, without touching the paratope or the VH-VL interface.

Same binder in any format
03

Proprietary Expression System

A proprietary expression architecture drives coordinated production of the heavy and light chains from a single modular construct, enabling efficient and reproducible antibody assembly.

Technical Milestones

August 2026
In progress

Milestone 1: Expression System Validation

Validate our proprietary expression architecture using several reporter system in HEK293T and CHO cell lines, confirming correct and efficient chain assembly.

September 2026
Planned

Milestone 2: First Antibody by Transient Expression

Apply our validated expression system to a full antibody construct and confirm entire and functional antibody production by ELISA and western blot.

November 2026
Planned

Milestone 3: Landing Pad Validation in Yeast

Construct and validate the modular landing pad system in S. cerevisiae as a BSL-1 proxy. Confirm integration by NGS and bridge to mammalian expression in CHO/HEK293T cells.
