Product Description / Introduction
This product utilize a dextran backbone to which multiple HRP enzyme and antibodies molecules are conjugated. This polymer creates a highly sensitive, readily available and one-step non-biotin detection system for immunohistochemical and immunocytochemical staining. This system avoids the use of streptavidin and biotin, and therefore eliminates non-specific staining as a result of endogenous biotin. It has a wide adaptability to sample processing, reducing the variability caused by different tissue processing methods. The reagent is ready-to-use, which does not need to be diluted to obtain the best staining ratio, reducing experimental operation errors.
Storage and Shipping Conditions
Wet ice packs for transportation, store at 2-8℃ for 12 months.
Assay Protocol / Procedures
