Therapeutic Antibody Discovery

When tasked with difficult therapeutic targets (cell surface, multispanning transmembrane proteins, glycoproteins, etc.) there are a few things that make Abveris uniquely equipped to deliver with the best chance of success. This includes our comprehensive services, immunization expertise, and access to leading discovery platforms.

COMPREHENSIVE SERVICES

EARLY PHASE

When working on unique targets, it may be difficult to find reliable reagents, namely proteins and/or cell lines. Our protein and cell line generation capabilities help to ensure that the appropriate amounts of immunization and screening materials are available. Once the project is complete, all remaining material are sent to our partners so that the materials can continue to be used as needed. 

MIDDLE PHASE - Discovery and screening

B Cell screening on Beacon and optimized hybridoma development processes enables the discovery of large, diverse sets of mAbs.

Our suite of high throughput screening and characterization platforms allows us to not only identify ideal binders, but also to screen for high-affinity and functionally relevant antibodies early in the discovery process. High throughput flow cytometry allows us to analyze on-cell binding as well as functional activity.

LATE PHASE

Next-generation sequencing efforts are accompanied by custom data reports that highlight developability concerns and deliver more value. Recombinant antibody production allows our partners the option to produce ample amounts of their favorite antibody in a reliable mammalian cell line. 

IMMUNIZATION EXPERTISE

Abveris prides itself on its expertise and breadth of immunization capabilities. Immunization methods include:

• Peptide/protein-based
• Cell-based 
• Subtractive cell-based
• DNA-based
• VLP-based
• Tolerance-breaking

The hyperimmune response of the DiversimAb mouse can generate appropriate titers in as little as 3 weeks, enabling rapid antibody discovery. Proprietary adjuvants and proprietary immunization protocols allow our team to exploit the hyperimmune and autoimmune features of our proprietary mouse strain for an even greater chance of cross-reactive and diverse antibodies sets. Through our work with different humanized platforms, we have optimized our immunization methods to apply to the mouse models commonly used for therapeutic discovery campaigns. 

LEADING DISCOVERY PLATFORMS

Abveris leverages a number of high throughput platforms for antibody screening and characterization. These platforms include TECAN systems for high throughput ELISA, iQue Flow Cytometry for high throughput on cell screening, Carterra SPR and Octet for antibody kinetics analysis. 

Anti-Idiotype Antibody Discovery

At Abveris, we deliver high-quality anti-idiotype antibodies using our DiversimAb^TM platform. We apply stringent, high content screening in relevant formats predictive of downstream assay success to identify quality reagents for your specific drug development assays (e.g. PK and ADA).

• High-speed offerings
• 94% success-rate delivering on our partner's goals
• Stringent screening packages
• Diverse assay candidates delivered

We know these mAbs are critical tools for clinical assay development, and the speed with which we deliver high-quality reagents ultimately impacts patients’ lives. Our team takes pride in the work we perform and prioritizes the delivery of the highest-quality antibodies in industry-leading timelines to support your clinical trials.

Cell Surface Targeting mabs

Our Secrets to Success

SELECT PROPER IMMUNOGENS
It is often challenging to present cell surface targets with proper
conformation and post-translational modifications. Abveris applies
innovative cell-based and DNA-based immunization protocols for
cell surface immunogens to maintain the integrity of their complex
structures. For certain targets and applications, recombinant
proteins and peptide strategies may also provide value.

ABVERIS DIVERSIMAB™ TECHNOLOGY
The proprietary Abveris DiversimAb™ mouse provides the best in
vivo option for generating monoclonal antibodies against membrane
targets. DiversimAb™ technology can be applied to generate diverse
panels of antibodies against tough targets, even when there are very
few surface epitopes available.
Abveris welcomes humanized mouse strains for fully human
therapeutic antibody discovery, or knockout strains at the request
of our partners.

HIGH-THROUGHPUT CELL BINDING ANALYSIS

The critical metric for success in antibody discovery for membrane targets is “on-cell binding,” thus necessitating frequent use of flow cytometry screening. The use of high-throughput flow cytometry technology unlocks the ability to screen massive panels of hybridomas with high resolution in hours instead of days.

GENE-TO-ANTIBODY

You provide the target and we will take it from there. Our antibody discovery expertise allows us to operate as an extension of your bench, complementing your capabilities.
