Cell-free synthesis of rat insulin-like growth factor II
AM Acquaviva, CB Bruni, SP Nissley and MM Rechler
Total RNA extracted from a rat liver cell line (BRL 3A) that synthesizes
rat insulin-like growth factor II (IGF-II) was translated in a reticulocyte
lysate cell-free system. Incubation of the translation products with
antisera to mature rat IGF-II (Mr 8700) selectively immunoprecipitated a Mr
21,600 protein. We propose that this protein represents pre-pro-IGF-II.
