Abstract
The process includes the steps of: a) contacting a liquid containing mRNA with an insoluble support having DNA probes attached thereto via the 5' -terminus thereof whereby the MRNA is hybridized to said probes and hence to said support; b) removing said liquid; and c) adding enzymes and nucleotides in solution whereby the probe functions as a primer to produce single stranded cDNA on the mRNA probe. The probe DNA may be oligo-dT or a specific DNA sequence, such as one that is complementary to a conserved region in a class of mRNA molecules. The insoluble support comprises magnetic particles which are monodisperse polymer particles comprising superparamagnetic iron oxide, a coating to reduce non-specific binding and a substituent for attaching an oligonucleotide.
