arrow12Section Block

A new class of blocking solutions based on chemically modified and fragmented ultra-pure casein. Effectively reduces unwanted binding of primary antibody and conjugates you use to charged surface of the slide and tissue section. Greatly reduces non-specific binding while preserving the specific reaction, by saturating potential non-specific protein-protein interactions. Moreover, in contrast to BSA-based, IgGm casein or serum-based blocking solutions there is no interaction of specific antibody and blocking protein itself.It is not comparable to other commercially available or home-made blocking solutions. Recommended for research and diagnostic pathology, especially for retrieved sections and polyclonal antibodies.

Epoxy resins are easier to section with glass, as well as diamond knives, when the embedding medium contains 0.5-1.0% of our SURE-CUT. The life of the diamond knife will be extended with its use because it will reduce the friction of the plastic block during sectioning.
