Manual Microdissection Combined with Antisense RNALongSAGE for the Analysis of Limited Cell Numbers

Establishing a gene expression profile of defined subtypes of cells within an or

Establishing a gene expression profile of defined subtypes of cells within an organ is still challenging because it frequently requires microdissection and subsequent amplification of the limited amount of messenger RNA (mRNA) isolated from the microdissected tissue in order to be able to proceed with comprehensive gene expression analyses via microarray or serial analysis of gene expression (SAGE) technology. Here we describe a manual microdissection strategy for the isolation of high-quality RNA. Furthermore, a strategy for combining linear amplification of RNA with longSAGE is described that allows the use of antisense RNA (aRNA) generated via the well-established linear amplification of RNA procedure together with the conventional SAGE or longSAGE technology.
