a Agarose gel electrophoresis showing double-stranded cDNA generated from fed and unfed Ctenocephalides felis fleas before and after Rsa I fragmentation. b Enrichment of cDNA products differentially associated with feeding by suppression subtractive hybridization (SSH). Subtraction was achieved by hybridizing adapter-ligated cDNA from fed fleas as the tester in the presence of an excess of unfed flea cDNA as driver. Unsubtracted fed flea cDNA products are shown for comparison
