The new lots of HRP-polymers contain a different red color which is more orange in order to distinguish HRP polymers and AP polymers. Properties and quality of the products will remain the same.
(HRP) Polymer anti-Rabbit
Enzym polymer single reagents with horse radish peroxidase. Ready-to-use.
Assay & Detection
Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Endogenous peroxidase activity in the tissue may cause non-specific staining. This enzyme activity can be blocked by incubation with 3% H2O2-solution (&S220;Peroxide block&S221;). Background staining caused by unspecific binding of the primary antibody or the secondary antibody in the HRP polymer is minimized by incubation with a protein blocking solution (&S220;Blocking Solution&S221;). This step can be omitted if the primary antibodies are diluted in an appropriate buffer. The next step is incubation with the specific primary antibody. After washing, the HRP-polymer is applied and incubated. Any excess of unbound HRP-polymer is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the horse radish peroxidase which leads to colour precipitation where the primary antibody is bound. The colour can be observed with a light microscope. The chromogen used determines the colour. The chromogen AEC leads to the formation of a red-brown product of reaction at the place of the target antigen. The chromogen DAB forms a dark brown precipitate.

6 ml / 60 Tests
The solution should be stored at 2-8°C without furt her dilution. Please store the reagent in a dark place and do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. They should not be used after the expiry date. A positive and a negative control have to be carried out in parallel to the test material.
