SuperBlock Blocking Buffer is an optimized solution containing a single purified glycoprotein that provides incredibly fast and effective blocking for ELISA, IHC, and western blot analysis. Blocking micro-plates, membranes, or tissues with a SuperBlock buffer yields a high signal-to-noise ratio in most detection systems.
Features of SuperBlock Blocking Buffer include:
Blocking time—block membranes in 5 to 10 minutes and ELISA plates in 2 minutes
Applications—ELISA, western blotting, IHC; biotin-free for use with streptavidin system
Stability—store buffer at 4°C for one year; store blocked plates dry for up to 12 months

Blocking micro-plates, membranes, or tissues with 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.

For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

What should I do about the colloidal carbon (black precipitate) in SuperBlock Blocking Buffer solution?

Allow any colloidal carbon, if present, to settle to the bottom of the bottle and pouring off what you need to use. We do not recommend centrifugation or filtering because these procedures may reduce the product's blocking capabilities.
