    Main Advantages

    SpecificHigh signal-to-noise ratio
    SensitiveDetects low-abundant targets due to an optimal number of HRP molecules per antibody
    High Signal AmplificationMultiple secondary antibodies can bind to a single primary antibody;Secondary antibodies Fc regions provide further binding locations for biotin, or enable the use of ABC and SABC
    FastGenerates strong signals in a relatively short time span
    QuantifieableAllows quantification of detected signal
    Easy to UseSupplied in a workable liquid format
    FlexibleHRP: compatible with chromogenic, fluorogenic and chemiluminescent substrates;
    ConvenientHRP’s small size: no interference with the primary/secondary antibody interaction; no steric hindrance to antibody/antigen complexes

    Background

    Most commonly, secondary antibodies are generated by immunizing the host animal with a pooled population of immunoglobulins from the target species. The host antiserum is then purified through immunoaffinity chromatography to remove all host serum proteins, except the specific antibody of interest, and are then modified with antibody fragmentation, label conjugation, etc., to generate highly specific reagents. Secondary antibodies can be conjugated to a large number of labels, including enzymes, biotin, and fluorescent dyes/proteins. Here, the antibody provides the specificity to locate the protein of interest, and the label generates a detectable signal. The label of choice depends upon the experimental application.

    Horseradish peroxidase (HRP) is extensively used for labeling secondary antibodies in ELISA, western blot, dot blot and immunohistochemistry. The HRP enzyme is made visible using a substrate that, when oxidized by HRP in the presence of hydrogen peroxide as an oxidizing agent, yields a characteristic change that is detectable by specific detection methods. The substrates commonly used with HRP fall into different categories including chromogenic, fluorogenic, and chemiluminescent substrates depending on whether they produce a colored, fluorimetric or luminescent derivative respectively. The intensity of the signal is proportional to peroxidase activity and is a measure of the number of enzyme molecules reacting, hence of the amount of recognized primary antibodies, and thus of the amount of target antigen.
