Guardian™ Peroxidase Conjugate Stabilizer/Diluent (Thermo Scientific™)

Thermo Scientific Guardian Peroxidase Conjugate Stabilizer/Diluent preserves the functional integrity and activity of horseradish peroxidase conjugated antibodies and other proteins at very dilute concentrations for long-term storage.

Features of Guardian Peroxidase Conjugate Stabilizer/Diluent:

Preserves HRP activity—no significant loss of HRP activity over a six-month period at room temperature (1:1000 dilution) or 12 months at 4°C
Convenient—store ready-to-use dilutions (1:1000 to 1:100,000) that maintain enzyme activity in the refrigerator—no aliquoting or freezing
Assay compatible—simply add your favorite blocking buffer to create the ideal diluent for your HRP-based ELISA system or store the HRP conjugate as a 1:1000 stock solution for Western blots and dilute in the final assay buffer
Saves money—less expensive than competitor formulations or ordering new HRP conjugates

With Guardian Peroxidase Conjugate Stabilizer/Diluent, typical 1 mg/mL antibody or streptavidin peroxidase conjugates can be diluted as much as 100,000-fold for storage at 4°C. Most ELISA and blotting applications for HRP conjugates require dilution of typical 1 mg/mL stocks by at least 1000-fold (to 1 µg/mL). Sensitive assay systems, such as with chemiluminescent substrates, often require dilution up to 100,000-fold (10 ng/mL). The Guardian Solution enables these 1X working concentrations of HRP conjugate to be prepared in advanced and stored at 4°C for 12 months or at room temperature for six months.For blotting applications, it is usually best to prepare a concentration for storage that can be diluted 10-fold in assay buffer (which may contain blocking components) for final use.

Typical colorimetric ELISA procedures requires that 10 mL of HRP-conjugated secondary antibody be diluted 1000- to 5000-fold from a 1 mg/mL stock solution. That necessitates pipetting 2 to 10 µL of stock into a tube with 10 mL of diluent. More sensitive assay systems, such as Western blots with Thermo Scientific SuperSignal West Pico, Dura or Femto Chemiluminescent Substrates for HRP, require a second round of dilution to achieve the needed working concentration of HRP conjugate. With Guardian Stabilizer-Diluent, HRP conjugates can be pre-diluted and stored at concentrations that are either ready to use or easily diluted 10- to 100-fold for final use. Preparing larger volumes of pre-diluted stocks ensures consistency and greater accuracy for assays performed repeatedly day after day.

Peroxidase Suppressor (Thermo Scientific™)

Thermo Scientific Pierce Peroxidase Suppressor is a stable, easy-to-use inhibitor of endogenous peroxidase activity from cells and tissues to reduce background signal in HRP-based immunohistochemistry applications.

Features of Peroxidase Suppressor:

• Stable
• One component
• Ready-to-use
• Effectively inhibits peroxidase activity without interfering with antigen-antibody
interactions

This peroxidase suppressor is optimized for immunohistochemical applications. The Peroxidase Suppressor is a stable, easy-to-use inhibitor of endogenous peroxidase activity. This proprietary formulation is the most effective peroxidase inhibitor available. The immunoperoxidase method is a commonly used detection method for immunostaining of cells and tissues. However, the analysis often is complicated by the presence of endogenous peroxidase and "pseudoperoxidase" activity in the cells and tissues. This presence results in nonspecific staining when a substrate such as diaminobenzidine (DAB) is present. Nonspecific staining is difficult to distinguish from the immunochemical marker, making it difficult to distinguish the final location of the antigen of interest. The typical method of inhibiting endogenous peroxidase activity involves hydrogen peroxide or hydrogen peroxide in methanol. The peroxidase suppressor inhibits peroxidase activity even more effectively than the method using hydrogen peroxide in methanol. Plus, the Peroxidase Suppressor does not affect antibody activity (see figure). Peroxidase Suppressor also can be used on blots of whole cell supernatant prior to the addition of the horseradish peroxidase (HRP) marker.
