Corrections to Preparation of Catalytically Active, Covalent α-Polylysine−Enzyme Conjugates via UV/Vis-Quantifiable Bis-aryl Hydrazone Bond Formation Andrea Grotzky, Yuichi Manaka, Taisuke Kojima, and Peter Walde* Biomacromolecules 2011, 12, 134−144. DOI: 10.1021/bm101074s Scheme 2 was published incorrectly. The correct Scheme 2 is as follows:

There was a mistake in the Materials and Methods section on p. 137, left panel, last paragraph, first sentence. The correct sentence is as follows: To determine A350 nm, a 500 μM 2-hydrazinopyridine reagent solution in MesB2 was prepared by diluting 10 μL of a 50 mM 2-hydrazinopyridine solution in anhydrous DMF with 990 μL of MesB2.
