New Formulation: HRP-Protector™
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 in between 40-200 ng/ml. If you have background or interference - for example derived from cross-reactivities - we recommend to use LowCross-HRP® as long-term stabilizer for the conjugate.
The even further improved formulation is indicated by the new cat. no.: #222.
The previous formulation is still available upon request (TRIS cat. no.: #220 050, #220 125, #220 500; PBS cat. no.: #225 050, #225 125, #225 500).
