Experimental setup:

Sixteen tissue samples were analyzed using 96 RealTime ready Assays, with 82 target genes from the apoptosis pathway, 8 reference genes, and 6 controls.

Results:

• LightCycler^® 1536 Software:
  a) Amplification data for all 1536 real-time PCR assays; b) Single analysis of 1 target gene (AKT1) in 16 tissue samples; c) Single analysis of 82 target genes in 1 tissue sample (small intestine)
• Downstream software:
  connectionParserd) Normalized ratios of 1 target gene (AKT1) in 15 tissue samples; e) Normalized ratios of 82 target genes in 1 tissue sample (small intestine)
