Neutravidin Coated Surface is ideal to bind any biotinylated molecules at wells of Neutravidin Coated Plates, with a minimal non-specific binding.

Neutravidin is a deglycosylated avidin (M.W. 60 kDa) that contains four identical subunits biotin-binding with very high affinity for biotin (Ka= 10-15 M).

It has an isoelectric point near-neutral (pI=6.3) and the lowest non specific binding properties among the known biotin binding proteins.

Compared to the streptavidin, neutravidin in its primary structure does not contain the RYD sequence (Arg-Tyr-Asp): the lack of such a sequence totally eliminates the possibility to interact with the RGD sequence (Arg-Gly-Asp) present in the membrane receptors of a large variety of cells. This makes it very useful in applications where it is important to avoid the non-specific interaction with the cell surfaces.

Neutravidin Coated Surface has similar binding capacity of Streptavidin Coated Surface for biotin and biotinylated molecules and offers a powerful and universal instrument for binding these molecules minimizing non-specific interactions. For example,  Neutravidin Coated Plates are suitable with ELISA assays protocol.
