Table 1 The number of ESTs, contigs and clusters differently expressed in L1 and iL3 stages and those with a two-fold or greater difference in expression.

From: A microarray analysis of gene expression in the free-living stages of the parasitic nematode Strongyloides ratti

  L1-up iL3-up Total
EST 1 659 1,244 1,903
≥ 2-fold 2 217 147 364
Contig 3 192 796 988
≥ 2-fold 4 50 69 119
Cluster 3 166 770 936
≥ 2-fold 4 37 62 99
  1. 1These ESTs are represented by 203 and 178 (L1-up) and 817 and 793 (iL3-up) contigs and clusters respectively.
  2. 2Number of ESTs that have a ratio of expression that is ≥ 2; these ESTs are represented by 72 and 60 (L1-up) and 82 and 75 (iL3-up) contigs and clusters respectively.
  3. 3 Number of contigs or clusters, respectively, in which at least one EST member (for which there were data above the quality threshold) had a significantly different ratio of expression.
  4. 4Number of contigs or clusters, respectively, in which at least one EST member (for which there were data above the quality threshold) has a significantly different ratio of expression that is ≥ 2.
