<jats:title>Abstract</jats:title><jats:p>Tris(2‐carboxyethyl)phosphine (TCEP) is an often‐used reducing agent in biochemistry owing to its selectivity towards disulfide bonds. As TCEP causes undesired consecutive side reactions in various analytical methods (e.g., gel electrophoresis, protein labeling), it is usually removed by means of dialysis or gel filtration. Here, an alternative method of separation is presented, namely the immobilization of TCEP on magnetic nanoparticles. This magnetic reagent provides a simple and rapid approach to remove the reducing agent after successful reduction. A reduction capacity of 70 μmol per gram of particles was achieved by using surface‐initiated atom transfer polymerization.</jats:p>
