Correction to: Top Down Tandem Mass Spectrometric Analysis of a Chemically Modified Rough-Type Lipopolysaccharide Vaccine Candidate
Correction to: J. Am. Soc. Mass Spectrom. (2018)
In the preceding article “Top Down Tandem Mass Spectrometric Analysis of a Chemically Modified Rough-Type Lipopolysaccharide Vaccine Candidate” by Oyler et al., an error in the J5 E. coli LPS chemical structure (Figs. 2 and 4) was introduced and propagated into the final revision. We did not notice this error until after the final galley proofing and apologize for this oversight. None of the figures or presented data interpretation are affected by this error; however, we wanted to make sure that the error in representation of the structure is not propagated through future research articles. On the second heptose residue in the core OS region of the ion, the original representation places a phosphate residue on the C-6 position. The phosphate residue is, in fact, located on the C-4 position of that same heptose as shown in the figure.
