In vitro translation of an intact mRNA coding for a poly(U), poly(C) specific ribonuclease isolated from six-day-old larvae of Ceratitis capitata by a modified extraction procedure.
Intact ribonucleic acid was prepared from six-day-old larvae of Ceratitis capitata, by enriching the guanidinium thiocyanate extraction procedure with a specific mixture for the active ribonuclease inhibition. RNA obtained by this means was then used as a source for the identification of mRNA coding for poly(U), poly(C) specific ribonuclease. The isolated poly(A+) RNA was translated in a cell-free protein synthesizing system. The presence of a poly(U), poly(C) ribonuclease among the newly synthesized products was detected by immunoprecipitation with anti-rabbit polyclonal antibodies against poly(U), poly(C) ribonuclease.
