The figures in the Protocol by Elbi et al. were only printing and displaying in black and white in the PDF. The figures online are displaying correctly. An updated PDF was created that allows the figures to display and print in color. The corrected PDF is available starting 06 July 2004.
The original, uncorrected PDF can be accessed from http://stke.sciencemag.org/cgi/data/sigtrans;stke.2382004pl10/DC1/1"
