This is a replacement product for CM53211. C6 Maleimide activated HRP is much more stable than previously offered product CM53211.nnCellMosaic’s C6 maleimide activated horseradish peroxidase (HRP) is designed for direct conjugation of HRP with proteins, peptides, or other ligands containing free sulfhydryl groups for use as an enzyme-linked detection reagent. This product consists of HRP that has been modified with EMCS (N-Ɛ-maleimidocarproyl oxysuccinimide ester, 9.4 Å spacer length) to attach 1 to 2 maleimide groups per HRP molecule while retaining the peroxidase activity. The activated HRP will covalently attach to sulfhydryl-containing compounds to generate the majority single labeled HRP-conjugates reporter probes. nnThe product is sold as 1 vial of 2 mg (Cat# CM53214-1x2MG) or 3 vials of 2 mg (Cat# CM53214-3x2MG).
