| Abstract: | Effect of complementary oligonucleotides and their reactive derivatives on translation of mouse immunoglobulin G kappa light chain was investigated. It was found that oligonucleotide pTGCTCTGGTTT and shorter oligonucleotides complementary to the coding sequence of the mRNA (nucleotides 205-215) do not arrest translation of the mRNA in the rabbit reticulocyte cell-free translation system. Preincubation of the mRNA with the alkylating 4-(N-2-chloroethyl-N-methylamino)benzyl-5'-phosphamide derivative of the oligonucleotide completely suppresses the synthesis of the protein thus demonstrating higher efficiency of the reactive oligonucleotide derivatives as inhibitors of the mRNA function. |
