Quality control probe of the S. haematobium protein microarray. Arrays were probed with (A) anti-hemagglutinin (HA) antibody to detect expression of the N-terminal HA tag and determine the percentage of protein expression from all arrayed antigens, and (B) anti-6-HIS antibody to detect expression of the C-terminal 6-HIS tag and determine the percentage of full-length protein expression from all arrayed antigens. No DNA refers to control spots where plasmid DNA (encoding genes to be expressed) is omitted from the reverse transcription-translational products printed at those locations. Sh Adult ES, S. haematobium adult fluke Excretory/Secretory products; Sh Adult PBS extract, S. haematobium adult fluke PBS-soluble somatic extract; Sh egg ES, S. haematobium egg ES products; Sh Adult triton extract, S. haematobium adult fluke TritonX-114-soluble extract; Sh SEA, S. haematobium soluble egg antigen.
