  1. Gene expression profile of selected peptidases in E. histolytica isolate HM-1:IMSS.
  2. For microarray analysis nine independent experiments were performed. The signal intensity is indicated in pixel. For real time PCR analysis all primer sets were run in duplicates. Two biological replicates were investigated. The expression of actin as normalizer was set to 1. The relative expression of the peptidases were related to actin.
