NHS-activated Sepharose(R) 4 fast flow is a pre-activated agarose matrix that increases the choice of coupling chemistries available. Suitable for coupling amino-containing smaller proteins and peptides.NHS-activated Sepharose(R) 4 fast flow is composed of cross-linked 4% agarose beads NHS activated for coupling amino-containing proteins and peptides in process-scale applications. NHS (N-hydroxysuccinimide) coupling forms a chemically stable amide bond with ligands containing primary amino groups.This resin provides a spacer arm to the coupled ligand and is therefore particularly suitable for immobilising smaller protein and peptide ligands.NHS-activated Sepharose(R) 4 fast flow is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development. As member of the BioProcess media range NHS-activated Sepharose(R) 4 fast flow meets industrial demands with security of supply and comprehensive technical and regulatory support.
