Amintra® Streptavidin Resin

Amintra® Streptavidin Resin – Ultra-high biotin binding capacity

Using an innovative immobilization technology, Amintra® Streptavidin Resin offers an ultra-high biotin-binding capacity with a very low leaching.

Constituted of pure recombinant streptavidin covalently cross-linked and immobilised on fine beaded agarose, Amintra® Streptavidin Resin can be used to bind biotinylated biomolecules in a variety of batch or column-type affinity procedures with low non-specific binding.
