title: Message amplification phenotyping (MAPPing): a technique to simultaneously measure multiple mRNAs from small numbers of cells.
abstract: A rapid and highly sensitive technique (MAPPing: message amplification phenotyping) has been developed to simultaneously analyze the array of messenger RNAs made by small numbers of cells. The technique incorporates a micro-procedure for isolating RNA, reverse transcription of total cellular RNA to produce cDNA, and enzymatic amplification of cytokine-specific DNA fragments using the polymerase chain reaction. In this study, the technique has been applied to the analysis of cytokines produced by lymphoid cells ranging in number from a single cell to 10(6) cells. The technique should be applicable to virtually any tissue or cell type.
