Thermo Scientific SuperBlock™ Blocking Buffer is optimised solutions in PBS or TBS containing a protein that provides incredibly fast and effective blocking for ELISA, IHC and Western blot analysis.

• Fast - block membranes in 5 to 10 minutes and ELISA plates in 2 minutes
• Flexible - guaranteed to be biotin-free for use with streptavidin system
• Low background - the non-serum protein solution yields a high signal-to-noise ratio
• Stable - store buffer at 4˚C for one year; store blocked plates dry for up to 12 months
• Product is shipped at ambient temperature

Blocking microplates, membranes or tissues with a SuperBlock Buffer yields a high signal-to-noise ratio in most detection systems. The protein-based formulation does not contain any immunoglobulins, albumin or endogenous biotin, making it compatible in many situations where traditional blocking agents fail. The buffer is especially effective at blocking coated polystyrene microplates (96-well plates) and stabilizing them for drying and storage for later use.
