Thermo Scientific SuperBlock (PBS) Blocking Buffer is optimized PBS solution containing a protein that provides incredibly fast and effective blocking for ELISA, IHC and Western blot analysis.

Features of SuperBlock (PBS) Blocking Buffer:

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
Convenience—available in multiple package sizes (100 mL, 1L and 5L)
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

Blocking micro-plates, 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.
