In the article "Quantitative analysis of ceramide molecularspecies by high performance liquid chromatography" by Drs. MidoriYano, Etsu Kishida, Yuka Muneyuki, and Yasuo Masuzawa whichwas published in the October 1998 issue of the Journal of LipidResearch (1998. 39: 20912098) incorrect wavelengths forfluorescence detection were recorded. On page 2092, right column,line 24, the correct excitation wavelength is 370 nm (not 365nm); on the following line, the correct emission wavelengthis 470 nm (not 412 nm). In the legend for Fig. 1 on page 2093,the correct wavelengths for excitation and emission are 370nm and 470 nm, respectively.
