Item Description Maleimide Activated Hrp 1/pk

The Thermo Scientific Maleimide Activated Horseradish Peroxidase (HRP) Kit can be used to directly prepare HRP conjugates from proteins, peptides or other ligands that contain a free sulfhydryl group. This kit eliminates the first step of the two-step maleimide method, making conjugate preparation much simpler. The kit is supplied with a stable, Maleimide-activated horseradish peroxidase. HRP conjugates can be purified by gel filtration chromatography, ultrafiltration or dialysis, depending upon the size of the conjugated protein.


  • Prepare enzyme conjugates from proteins that contain a free sulfhydryl
  • Includes 2-MEA to generate free sulfhydryls from disulfide bonds
  • Includes SATA to add free sulfhydryls to lysine residues
