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. or oth 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. Storage : 4-8°C Technical Data Sheet    

Container made of polypropylene – Closure made of polyethylene. This shatter resistant, especially designed for collection, transport and specimen storage.

This model uses a different tamper evident concept compared to the SecurTainer I above. No locking tab to push up is necessary when the tamper evident is used. Simply screw the cap on the container and the tamper evident sealing ring is automatically locking in place. When unscrewed, the ring is detached from the cap. All other features are the same as SecurTainer I. CapInserts are available in assorted colors.
