Transcription profiling to analyse the effect of the amount of human input total RNA on the fidelity, reproducibility, and yield of T7 based RNA linear amplification


ABSTRACT: This experiment was designed to evaluate the effect of the amount of input total RNA on the fidelity, reproducibility, and yield of T7 based RNA linear amplification. BC2 total RNA was amplified using the Jeffrey lab protocol. Different amounts of T7 primer were used according to the quantity of input total RNA. Multiple amplifications were done for each quantity of input total RNA to minimize experimental variations.

T7 based linear amplification of RNA is used to obtain sufficient antisense RNA for microarray expression profiling. We optimized and systematically evaluated the fidelity and reproducibility of different amplification protocols using total RNA obtained from primary human breast carcinomas and high-density cDNA microarrays.Using an optimized protocol, the average correlation coefficient of gene expression of 11,123 cDNA clones between amplified and unamplified samples is 0.82 (0.85 when a virtua  ...[more]
