Abstract
Vitellogenin mRNA was purified through three steps. A heavy polysome fraction was obtained by discontinuous sucrose density gradient centrifugation, vitellogenin polysomes were immunoprecipitated with affinity-chromatography-purified anti-lipovitellin IgG and goat anti-rabbit IgG, the enriched mRNA was isolated on a poly(U)-Sepharose column. As judged by its specific activity in a reticulocyte lysate system, vitellogenin mRNA has been enriched a 1000-fold with a recovery of 30%. On 99% formamide 3.4% polyacrylamide gels vitellogenin mRNA has an Mr of 2.4-2.5 X 10(6) and codes for a peptide of Mr 240000, which under our incubation conditions is partially degraded to smaller peptides.
