Add the 'IN THE LAB' feature, as previously described. To remind you, this 'IN THE LAB' feature should contain a small image of the western gel with all 15 lanes filled with samples (blue dye). A note should appear below the image that reads: 'Reminder: The gel only has 15 lanes and one lane must be reserved for the protein marker.' ('Reminder' is semi-bold, the rest is normal) and then add a 'Learn More' hyperlink that takes them to the reference library when selected. (Format this text like the text on the 'Select Techniques' page.) Decrease the width of the sample prep table and move it down as appropriate to fit this 'IN THE LAB' feature.
