AtaGenix Laboratories
AtaGenix’s naïve library technology enables rapid antibody discovery with high diversity (up to 10¹⁰ variants) while eliminating the need for animal immunization. Compared to hybridoma technology, our phage display approach reduces turnaround time to 3-4 months and removes the need for further humanization, ensuring efficient and cost-effective therapeutic antibody development.
Rapid Antibody Screening
Select high-affinity antibodies within 3-4 months, twice as fast
Animal-Free & Ethical
No animal immunization, fully human naïve library screening
No Further Humanization Needed
Direct selection of fully human antibodies, reducing costs

Explore real-world yeast protein expression case studies from AtaGenix. Our Pichia pastoris and Saccharomyces cerevisiae platforms deliver high-yield recombinant proteins with proper folding and glycosylation — supporting enzyme production, diagnostic antigen development, and antibody screening applications.
A 2021 Small Methods study used dual phage display libraries — an overlapping spike peptide library for epitope mapping and a 8.7×10⁹ patient-derived ScFv library for antibody discovery — to identify three immunodominant RBM epitopes (S431–454, S470–486, S501–515) and isolate human neutralizing monoclonal antibodies from COVID-19 patients. S470–486 emerged as the key protective epitope (diagnostic AUC ~1.0; mouse immunization produced neutralizing antibodies). AtaGenix provided phage library construction, biopanning screening, and antibody expression services that enabled the 10⁹-scale discovery campaign. DOI: 10.1002/smtd.202100058.
