High resolution: rare transcripts included! Transcript-species copy-numbers and distribution MACE Microarray
Massive Analysis of cDNA Ends: MACE Advantages • High-resolution: • only one specific tag is sequenced per transcript • even low-level expressed transcripts are analyzed • High SNP-coverage: • only the highly polymorphic 3’ ends are sequenced • high coverage for reliable SNP detection is warranted • High throughput & low costs: • hundreds of samples can be analyzed simultaneously • multiplexed sequencing reduces costs while still providing high resolution
