The Supplementary Information file published with this Article contained an error in the amounts used to prepare the Sorensens buffer, under the subheading ‘2. Buffered Lugol’s solution (B-Lugol)’.


“Before preparing the buffered Lugol’s solution, prepare a two times Sörensen’s buffer (pH 7.2). See below for the appropriate amounts and ratio.

266 mM Na2HPO4

71.52 gram Na2HPO4.5H20 in 1L bi-distilled water

266 mM KH2PO4

18.16 gram KH2PO4 in 1L bi-distilled water

Combine 71.5 ml Na2HPO4 with 28.5 ml KH2PO4 for a pH of 7.2.”


now reads:


“Before preparing the buffered Lugol’s solution, prepare a 266 mM Sorensen’s buffer (pH 7.2). See below for the appropriate amounts and ratio.

266 mM Na2HPO4

47.35 gram Na2HPO4.2H20 in 1L bi-distilled water

266 mM KH2PO4

36.20 gram KH2PO4 in 1L bi-distilled water

Combine 71.5 ml Na2HPO4 with 28.5 ml KH2PO4 for a pH of 7.2.”


This error has now been corrected in the Supplementary Information file that accompanies the original Article.
