Correction: Taliaferro, L. et al. Evaluation of the Broad-Range PCR-Electrospray Ionization Mass Spectrometry (PCR/ESI-MS) System and Virus Microarrays for Virus Detection. Viruses 2014, 6, 1876-1896

We have noted some inaccuracies in Table 1 and Table 2 of our article “Evaluation of the Broad-Range PCR-Electrospray Ionization Mass Spectrometry (PCR/ESI-MS) System and Virus Microarrays for Virus Detection” (Viruses 2014, 6, 1876–1896) [1].

In Table 1, the heading “LLMDA” was omitted and needs to be added to correctly align the results obtained using the LLMDA and the ViroChip with their corresponding results. Additionally, the 10⁻⁷ RNA dilution sample needs to be corrected to indicate that it was not tested (nt) in the presence of 10⁵ cell equivalents of Sf9 total nucleic acids (+10⁵) by the PLEX-ID.

In Table 2, the results for LLMDA need to be corrected to indicate that 10⁻⁴ RNA dilution was tested and found to be negative, whereas the 10⁻⁶ RNA dilution was not tested (nt).

Below you will find the corrected Table 1 and Table 2 for our recently published article [1]. We apologize to the readers of Viruses for any inconvenience this may have caused.
