  • More sensitive than ABTS and OPD
  • Develops deep blue color measurable at 650 nm
  • Turns yellow when stopped with acid (read at 450 nm)
  • Two-component format for extended shelf life
  • Suitable for ELISA and membrane blotting (with enhancer)
  • ISO 13485-certified quality

Applications

  • High-sensitivity ELISA assays
  • Low-abundance target detection
  • Antibody and antigen quantification
