Effects of template switching (TS) primer and cDNA cleanup columns on T7 based RNA linear amplification


ABSTRACT: Zhao et al. Amplification Table 1 This experiment was designed to determine the effects of template switching (TS) primer and the type of columns used in ds cDNA cleanup on the fidelity of the T7 based RNA linear amplification. BC91 total RNA was amplified with or without TS primer and with two different ds cDNA cleanup protocols. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Computed

<h4>Background</h4>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.<h4>Results</h4>Using an optimized protocol, the average correlation coefficient of gene expression of 11,123 cDNA clones between amplified and unamplified  ...[more]
