Description
Durastab™ HRP Stabilizer is a horseradish peroxidase (HRP) conjugate dilution/stabilizer, used to prepare HRP working solutions that remain stable during long-term storage at 2–8 °C.
Application
ELISA / Chemiluminescence: Used for diluting HRP-labeled detection antibodies.
Western blot / Microarray / IHC: Serves as the diluent for HRPconjugated secondary antibodies.
Instruction
Durastab™ HRP Stabilizer is ready-to-use and should be equilibrated to the reaction temperature before application.
Prepare the HRP working solution by diluting the HRP conjugate to the desired concentration according to the user-defined dilution ratio.
It is recommended to validate performance within specific assay systems prior to full-scale use.

FAQ
Q1: How does Durastab™ HRP Stabilizer maintain antibody conjugate stability during long-term storage?
A: Durastab™ HRP Stabilizer utilizes a specially formulated MOPS buffer system (pH 6.4 ± 0.4) with BSA to prevent enzyme denaturation, conformational changes, and activity loss. Pre-diluted HRP-conjugated secondary and primary antibodies retain over 90% catalytic activity after 3 years of storage at 2–8°C.
Q2: Can Durastab™ HRP Stabilizer be used as a direct alternative to commercial HRP diluents like StabilZyme®?
A: Yes. Durastab™ HRP Stabilizer (Art. No. HRST) serves as a high-performance, drop-in replacement for StabilZyme® and LifeXtend® HRP stabilizers. It offers equivalent signal retention, lower background interference in high-sensitivity ELISA and Western Blotting, and cost-effective bulk pricing ($140/L).
Q3: Is this HRP stabilizer suitable for both ELISA and Western Blot applications?
A: Absolutely. It is designed as a universal working diluent for HRP-labeled detection antibodies in sandwich ELISA, chemiluminescent Western Blotting, IHC, and microarray assays, providing high signal-to-background ratios.
