Finding cDNA clones

Several partly overlapping initiatives have been generating and providing cDNA clones, i.e. reverse transcribed copies of mRNAs. Due to the academic or academic+commercial backbone of these enterprises, clones are available for relatively low costs, typically around 70€/50£/?$. As of 2008, clones are provided in Europe by GeneService and imaGenes (prev RZPD), and in N America by the ATCC/LGC Promochem.
