Transform your bioanalytical assay development with TrailBlazer Antibodies


Discover how your bioanalytical assays can be transformed with site-specific conjugated antibodies in multiple formats, made using SpyTag technology and custom HuCAL® recombinant antibody generation.

The antibodies used in bioanalytical assays are critical for optimizing selectivity and sensitivity. Having an antibody in only one format can limit your options and producing well-characterized conjugated molecules can be difficult, costly and delay your progress. Learn how SpyTag-SpyCatcher technology has been incorporated with custom HuCAL® recombinant antibody generation to make ‘TrailBlazer Antibodies’. This innovative combination enables site-directed conjugation of antibodies and rapid assembly of different stable 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.
