Antibody development and engineering

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.

Let's discuss antibody development!

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.

RAPID
TIMELINES

RAPID TIMELINES

Affinity maturation takes 4-8 weeks, depending on using a rational strategy, or an unbiased strategy.

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.

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.

FLEXIBILITY

Antibody variable regions from the light (VL) and heavy (VH) chains can be humanized from any species.

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.
