Peroxidase (HRP) Substrates

Vector Laboratories offers two lines of Horseradish peroxidase (HRP) substrates.

Our original HRP substrate kits:

  • Provide sensitivity greater than conventional substrates
  • Are known for their consistency and reliability
  • Supplied as concentrated stock solutions in convenient dropper bottles, stable for one year

The ImmPACT® line of HRP substrates offers the following advantages:

  • 2-4 fold greater sensitivity than the original substrate kits
  • Supplied with stock solutions in dropper bottles and optimized diluent
  • Optimized specifically for immunohistochemistry applications
  • Stock solutions stable for one year, working solution stable for up to 14 days at 4 ºC
