Development of immunoassays is complex and time consuming. The antibodies you use play a critical role in optimizing selectivity and sensitivity. Having an antibody in only one format can limit your options and producing several different conjugates or alternative formats can be tedious, costly and delay your progress. 

In this webinar, Dr. Francisco Ylera, R&D Team Leader at Bio-Rad Laboratories, explains how he incorporated the SpyTag-SpyCatcher technology into the custom HuCAL® recombinant antibody generation service to make 'TrailBlazer Antibodies'. This innovative combination of technologies enables site-directed conjugation of antibodies and rapid assembly of different Fab and full-length formats. The outcome is an extensive antibody toolbox in your hands that provides multiple options for assay design, with the added advantage of a consistent, long-term supply of non-animal-derived antibodies. Join the webinar to learn how TrailBlazer Antibodies can transform your assay development.


Key learning objectives

  • Learn what SpyTag-SpyCatcher technology is
  • Discover how it is used with Bio-Rad’s custom recombinant antibodies
  • Understand how it enables site-directed conjugation and rapid assembly of different antibody formats
  • See performance data for different assays

Who should attend?

  • Research scientists in any organization using antibodies in assays to quantitate or locate specific antigens in applications such as ELISA, flow cytometry, western blotting and immunofluorescence
  • Scientists seeking custom antibody reagents designed for their specific project needs, when there are none available or their currently used reagents are not fit for purpose

Certificate of attendance

  • All webinar participants can request a certificate of attendance and a learning outcomes summary document for continuing education purposes.

Francisco Ylera leads the R&D team at Bio-Rad AbD Serotec GmbH which focusses on optimization of the monoclonal antibody generation platform. His team combined the SpyTag-SpyCatcher technology with HuCAL® antibody library and phage display to enable fast antibody assembly and site-directed conjugation.

He studied chemistry in Aachen (Germany), did his Ph.D. at the Department of Biochemistry in Berlin, and a postdoc at the Harvard Medical School (USA). He joined Roche for the development of a cell-free protein expression system. Since 2004 he has been at Bio-Rad and worked for many years on custom antibody generation and internal projects before he took over the R&D team.
