Atlas™ Mouse Technologies

Atlas™ Mice were developed by the AbTherx team and are licensed as part of an exclusive partnership with Gilead. Learn more

We built a better mouse

Full Human Diversity Mouse was thoughtfully designed to overcome many of the challenges with legacy transgenic technologies.

  • Full-diversity human HC + κ-LC
  • Using only functional VH/VK promotes more productive B-cell rearrangements
  • Variable sequences used avoid patented or FTO-excluded variants
  • V-regions used comprise >99% of commonly expressed human sequences

Bispecific antibodies inspired by nature

Binary Fixed Light Chain Mouse enables the development of a clinically validated bispecific antibody format that is most similar to native antibodies.

  • Most similar structure to a native Ab
  • Allows target-driven selection from one of two fixed LC cassettes
  • Increases hit recovery – two LCs have overlapping but distinct abilities to pair with diverse HCs
  • Novel mechanism where individual B cells can only express one of two Vκ genes

Target GPCRs and ion channels with long CDR3s

Long CDR3 Mouse uses natural mechanisms to generate long CDR3 antibodies to improve the chance of success against GPCRs and ion channels.

  • Addresses an unmet need: a new technology enabling access to GPCRs and ion channels
  • Natural mechanisms are co-opted for obligate long H-CDR3s
  • Improves upon platforms having immunogenicity or expression issues



Our team leads the industry with over 1,000 successful antibody discovery programs and 13 marketed therapeutics.

Assistant Professor and Underwood Prescott Career Development Chair, Massachusetts Institute of Technology
Co-founder, BioBits®
Postdoctoral Fellow, Stanford University
PhD, Northwestern University

Dr. Stark’s career is marked by her pioneering work in developing biological technologies to unlock the vast potential of cell-surface sugars, known as glycans, for immunological discovery and immunotherapy. Glycans form a protective layer on the surface of every cell, influencing immunological processes. Despite their significance, drug developers’ ability to identify the specific glycans that regulate immune responses and design targeted therapies remains limited. Dr. Stark’s lab is at the forefront of efforts to comprehend and manipulate the roles of glycans in the immune system, aiming to 1) bridge crucial gaps in immunobiology and 2) forge the path for next-generation immunotherapies.

As a postdoctoral fellow with Nobel Laureate, Professor Carolyn Bertozzi at Stanford University, Jessica’s work focused on identifying and targeting glycans. She is a co-inventor of antibody-lectin chimeras (AbLecs), a modular platform for glyco-immune checkpoint blockade. She received her PhD in chemical and biological engineering with Professor Michael Jewett at Northwestern University. Dr. Stark is currently an Assistant Professor in the departments of Biological and Chemical Engineering at MIT and an intramural faculty member in MIT’s Koch Institute for Integrative Cancer Research.
