Expression of mRNAs microinjected into somatic cells.

J E Celis

    Ciba Foundation Symposium
    |January 1, 1984
    PubMed
    Summary

    Microinjection delivers macromolecules into cells to study their biological activity. This method was used to analyze messenger RNA (mRNA) expression in cultured cells, revealing successful translation of globin and other mRNAs.
