Asymmetrical Structure
Bispecific Antibodies (BsAb) exhibit poor manufacturability and challenging analytics
S-DUAL™ addresses these issues through its unique structure and properties
- The Problem of BsAbs: Mispairings
-
- Standard BsAb - Desired BsAb
- 8 Possible BsAb Combinations - Probability of correct pairing: 1/8
- Mispairings > Poor peak separation > Process & Analytical issues
-
- Similar physiochemical properties of mispaired BsAb result in difficult peak separation
- Challenging purification, analytics and poor productivity
- S-DUAL™: Address BsAb Mispairings

S-DUAL™ BsAb Platform Structure
Asymmetric antibody structure, along with knob-and-holes at the CH3 regions, assures that only your desired BsAb is produced without mispairings.
S-DUAL™ platform expresses BsAb from a single cell line, reducing operational complexity.
Correctly Paired bsAb
Impurities are removed with ease through standard purification methods
- SEC-HPLC: Consistent purities in excess of 98%
- Reducing CE-SDS: Main peak is comprised of the expected ratio of LC/HC, demonstrating correct LC/HC pairing of intact BsAb

Low Immunogenicity Risk
S-DUALTM consists of components derived from human immunoglobulin
In silico models support the low immunogenicity of BsAb resulting from the S-DUALTM platform
