Figure 7

Comparison between first and last print with the same stamp. (A) shows the fluorescent image of the patterns transferred at the first print, and (B) shows the printing patterns after 5^th (B1), 6^th (B2) and 7^th print (B3). Stamps were inked with a 15-mer 5'-labelled Cy5 oligonucleotide for 30 sec and then set in contact for 2 min with the dendrislide. The well defined features is shown in (A) whereas only the rims of the patterns were detected after the 4^th print (B).
