A method for isolating mRNAs as cDNAs employs a polymerase amplification method using at least two oligodeoxynucleotide primers. In one approach, the first primer contains sequence capable of hybridizing to a site immediately upstream of the first A ribonucleotide of the mRNA's polyA tail and the second...http://www.google.com/patents/US5599672?utm_source=gb-gplus-sharePatent US5599672 - Method of differential display of exposed mRNA by RT/PCR
