Purification and characterization of the neu/erb B2 ligand-growth factor from bovine kidney.


A neu/erb B2 ligand growth factor (NEL-GF) was purified to homogeneity from bovine kidney by a procedure involving ammonium sulfate fractionation (35-70% saturation) followed by sequential column chromatography on DEAE-cellulose (DE52), Sulfadex (sulfated Sephadex G-50), heparin-Sepharose 4B, and Superdex 75 (fast protein liquid chromatography). NEL-GF was… (More)
