ATEM Structural Discovery developed a machine learning-based algorithm that transforms cryo-EM LNP images into quantitative morphological insights, delivering results within two weeks.

ATEM is a specialist cryo-EM CRO working exclusively in biologics development. We answer the specific structural and morphological questions that block pharma and biotech teams from advancing their programs — delivering panel-ready, decision-ready results at the speed development timelines demand.  Our work spans three active product areas:   * LNP characterization, where AI-enabled morphological analysis translates particle population data into formulation and process development decisions.   * High-Throughput 3D Epitope Mapping, where structure determination of antibody-antigen complexes — including membrane protein targets — delivers mechanistic interpretation and actionable design recommendations for antibody engineering and discovery biology teams.
  * GMP Viral Contamination Testing, where morphological analytical assays under GMP conditions produce regulatory-defensible evidence for IND, BLA, and cell bank qualification submissions. 
 Unlike generalist analytical providers, ATEM scopes every engagement to the question being asked — not the broadest analysis that can be justified. The deliverable is always the same: a clear answer to the client's development question, documented for regulatory or internal use, and interpreted in language the development team can act on directly.  To find out more about ATEM, visit www.atem.bio
