Comparison of different technologies available for ncRNA analysis.

Method	Throughput	Cost	Transcript abundance	Produce absolute results	Require a priori knowledge	Accuracy of results
RNA-sequencing	High	Low	Low	Yes	No	High
DNA microarrays	High	Low	High	No	Yes	Depends on transcript abundance
Genomic tiling arrays	High	Low	Low	Yes	No	High
Tissue microarrays	Very high	Low	Low	No	Yes	High
Northern blotting	Low	Low	High	No	Yes	Low
