Partial purification of rat alpha-lactalbumin mRNA

|June 1, 1977
Abstract:
Alpha-lactalbumin messenger RNA was partially purified from RNA extracted from 3-5 day lactating rat mammary glands on a poly(U)-sepharose column followed by sucrose gradient centrifugation. Apha-Lactalbumin mRNA activity was assayed in wheat germ cell-free translational system by immunoprecipitation of the in vitro synthesized protein using specific antiserum prepared against purified rat alpha-lactalbumin. In the purified mRNA preparation alpha-lactalbumin mRNA activity comprised approximately 85% of the total mRNA activity.
