HRP-Protector™ is a long-term stabilizer for horseradish peroxidase (HRP) coupled to antibodies or Neutravidin/Streptavidin. HRP-Protector™ gives peroxidase conjugates the crucial long-term stability over several years even when stored in low concentrated ready-to-use dilutions. HRP-Protector™ can be used directly as an assay buffer for incubating the HRP-conjugates.
Typical ready-to-use concentrations for detection are between 40-500 ng/mL.
If you have background or interference - for example derived from cross-reactivities - we recommend using LowCross® HRP-Stab as long-term stabilizer for the conjugate.
