title: Synthesis of full-length cDNAs from partially purified human procollagen mRNAs.
abstract: Partially purified human procollagen mRNAs have been copied using reverse transcriptase from avian myeloblastosis virus. Under standard conditions, using a high deoxynucleotide concentration, only incomplete cDNAs corresponding to one-fifth to one-half of the template could be synthesized. Addition of a ribonuclease inhibitor from human placenta in the reaction mixture allowed the synthesis of full-length cDNA copies from extremely long procollagen mRNA.
