That's why Mosaic Biosciences has partnered with [AbTherx](https://www.abtherx.com/) to provide exclusive access to their revolutionary [Atlas](https://www.abtherx.com/) Full Human Diversity (FHD) transgenic mouse platform.   The industry-leading FHD platform in combination with Mosaic's full stack discovery workflow - including proprietary phage-to-yeast display libraries - delivers partners broader epitope coverage, greater sequence diversity, and higher-quality therapeutic candidates through comprehensive *in vivo* and *in vitro* antibody discovery and engineering services.  [![AbTherx Slides Mock Up for lander -1](https://mosaic.mosaicbio.com/hubfs/AbTherx%20Slides%20Mock%20Up%20for%20lander%20-1.png "AbTherx Slides Mock Up for lander -1")](https://www.mosaic.com) As the sole provider of this mouse model, Mosaic eliminates the need for partners to work with multiple service providers. We deliver a fully integrated discovery powerhouse under one roof. What's more, our milestone- and royalty-free access model provides unparalleled flexibility for teams advancing new therapeutics powered by the FHD advantage.   Our industry veteran drug hunters dive into the science with you, leveraging the Atlas platform to transform concepts into drug candidates through close collaboration and unprecedented industry experience. From ideation to IND-enabling studies and everything in between, Mosaic delivers a true partnership experience that advances your programs with exclusive access to the most sophisticated antibody discovery platforms in the industry.

Ultimately, this comprehensive approach maximizes the chances of clinical success. [![AbTherx lander graphic 2 -1](https://mosaic.mosaicbio.com/hs-fs/hubfs/AbTherx%20lander%20graphic%202%20-1.png?width=1277&height=375&name=AbTherx%20lander%20graphic%202%20-1.png "AbTherx lander graphic 2 -1")](https://www.abtherx.com/) By combining Mosaic’s proprietary phage-to-yeast display libraries with AbTherx’s Atlas Full Human Diversity (FHD) transgenic mouse platform, we capture a breadth of human-like antibody diversity, uncovering epitopes that single-platform approaches might miss. The superior genetic diversity across both platforms translates into a richer set of unique antibody sequences, significantly increasing the probability of identifying high-quality, therapeutically relevant candidates. Starting with human-like antibodies from both *in vivo* Atlas FHD and *in vitro* phage-to-yeast methods, lowers developability risks and shortens timelines, driving a more efficient path toward clinical success.
