  • 特記事項

    This new and innovative HRP-polymerization technology provides a significant increase in staining sensitivity when compared to other conventional HRP-conjugated secondary antibodies. Avidin-biotin blocking procedures are not necessary when using this product. The overall staining procedure uses one less reagent (streptavidin peroxidase) and rinsing step, eliminates avidin-biotin blocking procedures and may reduce overall staining time.
