From antibody humanization and reformatting to afucosylated bispecific antibodies – we have developed and produced them all. Our technology and experience gives us an ability to discover antibodies against difficult multi-pass transmembrane proteins.
Icosagen provides antibody discovery and development services, using proprietary technologies.
We engineer diverse modalities of bispecific and multispecific antibodies, seamlessly integrating knowledge with practical expertise in structural and computational biology, bioinformatics in engineering, and production with tailored purification strategies.
Our rich expertise in engineering and format design, enables us to assess the feasibility of different combinations and designs, distinguishing between those with potential and those that may pose limitations.
To optimize therapeutic potential of a selected lead candidate, we can enhance or decrease its affinity, improve binding specificity to prevent off-target effects, mitigate aggregation and reduce immunogenicity through humanization. Further, we can modulate its half-life, immune cell binding and activation, and meticulously examine each molecule using tailored in vitro and in vivo assays.
Why choose Icosagen for bispecific antibody engineering?
ENGINEERING EXPERTISE
ENGINEERING EXPERTISE
Designing bispecific and multispecific antibodies involves multiple engineering steps to ensure molecules with precise multi-target binding specificities and affinities, while ensuring molecule stability, functionality and productivity profile, to name a few. This demands intricate molecular engineering skills and full understanding of structural biology to balance complexity and efficacy.

Affinity maturation and engineering
We can rationally assess different antibody projects to find right strategies towards generation of high affinity antibodies.
Our proprietary platform has undergone thorough testing and analysis, and when coupled with expert manual execution, has demonstrated outstanding effectiveness in enhancing antibody affinity and specificity.
Affinity maturation can be combined with antibody humanization.
Why choose Icosagen for affinity maturation?
RAPID TIMELINES
RAPID TIMELINES
Affinity maturation takes 4-8 weeks, depending on using a rational strategy, or an unbiased strategy.
RATIONAL ENGINEERING
RATIONAL ENGINEERING
Is key for the affinity maturation to succeed. We will design and generate libraries, assisted by the structure-based computational analysis containing soft-randomization in key positions to increase the chances to improve affinities.
DEVELOPABILITY PARAMETERS
DEVELOPABILITY PARAMETERS
For therapeutic as well as any other purposes, the developability is crucial - we can humanize and engineer mAbs to improve their solubility, thermostability, in addition to affinity.
Affinity maturation and engineering workflow
Humanization of antibodies discovered from non-humanized animals or libraries is a necessity for their use as therapeutics. The challenge is to retain the desired specificity and affinity, while engineering away their immunogenic properties.
Antibody humanization
Our humanization platform service benefits from a proprietary software developed in collaboration with the University of Tartu.
We routinely humanize variable regions and framework sequences from any species, using any reference sequence as the basis. Key residues important for the VH/VL interface and antibody structure are maintained as much as possible in the humanized variants. Humanized sequences are screened to be free of motifs that are prone to glycosylation, deamidation or other PTMS.

Antibody variable regions from the light (VL) and heavy (VH) chains can be humanized from any species.
VALIDATED SYSTEM
VALIDATED
In-house humanization and production cycle studies have provided antibodies with great titers and affinity database. We humanize all unconsolidated and non-human immunoglobulin variable region sequences.
FREE OF SEQUENCE LIABILITIES
