Hit Expansion with Reptor

Expand Candidate Hits Using NGS

Missing out on diversity in your antibody discovery campaigns? Want to perform antibody optimization that is informed by nature?

Abterra Bio now offers companion bulk sequencing as a parallel service to our hybridoma sequencing. Hit expansion helps engineer better sequence diversity of candidates to evaluate, reducing wasted effort on analysis of identical candidates and increasing chances for success.  Learn more about how Reptor can discover more relatives of hits from an antibody campaign in our recent case study. 

    Key Benefits of Hit Expansion:

    10-100x more antibody candidates per campaign

    Informed engineering based on observed sequence diversity

    Antibody hits with diverse mutation profiles, mutation loads, and liabilities

    Amplifying antibody sequencing and discovery


    Reptor Hit Expansion Sequencing acceptable species and sample types
