KPL HRP Stabilizer is effective at stabilizing peroxidase conjugates in diluted form for extended periods of time with minimum effect on conjugate activity. Stability studies conducted have indicated the HRP Stabilizer retains greater stability of diluted HRP conjugates than 50% glycerol, BSA or other commercially available products when stored at 37 C, room temperature or 4 C. Conjugates may be diluted to a use dilution concentration as low as 1 ug/mL and be stable for at least6 months when stored at 4 C. Product in ready-to-use liquid form.
