The World Stamp Championship was held in Singapore in 2004, and for each year in 2002, 2003 and 2004, Singapore Post issued 5 miniature sheets, each with 2 stamps and a label carrying a different corporate advertisement. For 2004, one of advertisers was GSK or Glaxo-Smith-Kline, a big pharmaceutical corporation; and its advertisement shows a gloved hand holding a DNA microarray with a typical image of DNA microarray result as the background. Now a DNA microarray consists of microspots of single stranded polymeric DNA molecules attached to a glass slide, and can be used to analyze the expression levels of the corresponding genes of a test subject.
