Four commercial protocols for amplification of picograms amounts of input RNA for microarray expression profiling were evaluated and compared. For each protocol, one RNA amplification was performed from 250 pg, and one from 500 pg of human universal RNA by two operators in two independent laboratories and compared to the amplified aRNA obtained from 2 µg and 100 ng RNA inputs following the standard protocol proposed by Affymetrix. A negative control (amplification without total RNA) and a positive control (if available) were included in each experimental batch. Samples indicating 50, 100, and 1000 pg RNA inputs correspond to 3 additional quantities of total RNA used to synthesise the cDNA target using the nugen protocol for comparison (250, 500 pg + 50, 100, 1000 pg).
