Amintra® NHS activated

Amintra® NHS activated is a bead formed, highly crosslinked preactivated matrix prepared by coupling Amintra® NHS activated with 6-aminohexanoic acid via a spacer arm, specifically designed for affinity purification. The terminal carboxyl group is activated by esterification with N-hydroxysuccinimide. Ligands containing primary amino groups couple directly to this active ester to form a chemically very stable amide linkage. To maintain high activity, Amintra® NHS activated is supplied as a suspension in 100% isopropanol, which should be washed away before use. Specific regulations may apply when using this product since it can require the use of explosion proof areas and equipment.
