Transcription profiling of Strongyloides ratti larval stage 1 (L1) vs infective larval stage 3 (iL3)
Ontology highlight
ABSTRACT: Isofemale line ED321 Heterogonic was used. Fresh faeces were collected from S. ratti-infected rats at days 5, 6, 7 and 8 p.i. and L1s prepared with a Baermann funnel held for 6 h at 19oC. The larvae were concentrated by centrifugation and then cleaned by flotation on 60% v/v sucrose. Infective L3s were harvested from 14 day-old faecal cultures that had been maintained at 19oC. The iL3s were cleaned by sucrose flotation as for the L1s, above. In excess of 150,000 larvae of either stage were routinely isolated from 6 infected hosts. The experimental design used, was to have at least three biological replicates for each sample (i.e. three independent preparations of the relevant worm samples and their RNA) and to have at least three technical replicates (i.e. independent, separate cDNA synthesis, amplification and hybridization etc.) for each biological replicate. For each hybridisation a dye-swap was used i.e. each sample to be used in a hybridisation was labelled, separately, with each of the two dyes.
