Puromycin CPG

One of the most challenging requirements associated with combinatorial chemistry is the recovery of sequence information of the oligonucleotide or peptide selected by the screening assay.  A method1 has been developed to generate a fusion product between mRNA and the polypeptide it encodes using in vitro translation of synthetic RNAs 3’-labeled with puromycin, an antibiotic that mimics transfer RNA.  Puromycin binds in the ribosome’s A site, forms a peptide bond with the growing peptide chain, and blocks further peptide elongation.  By linking puromycin to mRNA, a peptide-RNA fusion product results from the translation of the message linking the encoding mRNA with its peptide product.
