Abstract:Until recently, transcriptome analyses of single cells have been confined to eukaryotes. The information obtained from single cell transcripts can provide detailed insight into spatiotemporal gene-expression, and could be even more valuable if expanded to prokaryotic cells. Transcriptome analysis of single prokaryotic cells is a recently developed and powerful tool. Here, we describe a procedure that allows amplification of the total transcript of a single prokaryotic cell for in-depth analysis. This is performed by utilizing a laser capture microdissection instrument for single cell isolation, followed by reverse transcription via Moloney Murine Leukemia virus, degradation of chromosomal DNA with McrBC and DpnI restriction enzymes, ss-cDNA ligation using T4 polynucleotide kinase and CircLigase, and polymerization of ss-cDNA to ds-cDNA by ϕ 29 polymerase. This procedure takes ~5 days, and sufficient amounts of ds-cDNA can be obtained from single cell RNA template for further microarray analysis.
