Correction to “Thermodynamic Characterization of Polypeptide Complex Coacervation” Dimitrios Priftis,* Nicolas Laugel, and Matthew Tirrell Langmuir 2012, 28(45), 15947−15957. DOI: 10.1021/la302729r

n this work on the thermodynamic characterization of polypeptide complex coacervation, a series of poly(glutamic acid) and poly(aspartic acid) polymers with different molecular weights were used. In numerous occasions throughout the article (e.g., abstract, introduction), these polymers were referred to as poly(L-glutamic acid sodium salt) and poly(Laspartic acid sodium salt), implying that they were optically pure. After communication with the supplier (Alamanda Polymers, Inc.) and performing further characterization, it has come to our attention that these polymers were not optically pure (L) but contained a number of D repeating units and should therefore be referred to as poly(D,L-glutamic acid sodium salt) and poly( D , L -aspartic acid sodium salt), respectively. This recent realization of the racemic nature of the polyanions used does not affect any of the findings or the conclusions of this study.
