Antibodies and Microarrays

Antibodies are important tools in many research and diagnostic applications.
Zedira offers antibodies – polyclonal as well as monoclonal – raised against:

  • All human transglutaminases
  • Guinea pig liver transglutaminase
  • Bacterial transglutaminase
  • The transglutaminase reaction product: Nε-(γ-glutamyl)-L-lysine-isopeptide bond
  • Fibrinolytic enzymes: Plasmin and its zymogen (plasminogen)
  • Gliadin-variants

Antibody epitope mapping
PEPperPRINT and Zedira proudly present the new PEPperCHIP® Transglutaminase Microarray!
Standard and Custom PEPperCHIP® Peptide Microarrays are synthesized with a unique laser printer-based method directly on-chip and are used for antibody epitope mapping, immunological research, and biomarker discovery.

Antibodies labeled with fluorescent dyes
Zedira provides many of its polyclonal antibodies with a fluorescent label like FITC or phycoerythrin or as a biotinylated version. Of course, antibodies with other tags are available on demand.
