Our Technologies

xPloration   Screening Platform


Our xPloration B cell screening platform enables us to perform functional screens on a groundbreaking scale, measuring functional activity of millions of antibody variants within hours. This single cell platform evaluates the function of full-length soluble antibodies against disease-relevant cell models. 

xEmplar   Human Antibody Library


Our xEmplar library is a fully human scFv antibody library precisely designed to replicate the natural immune repertoire with an eye for improved developability. We have eliminated problematic amino acid motifs from our library to minimize downstream antibody aggregation and non-specificity. Optimal CDR compositions and ideal framework selection, combined with decreased aggregation and off-target reactivity, result in a library that yields many high-affinity and developable hits.


Highly Developable


We partner with leading biotechnology companies and academic institutions to discover impactful antibodies.
