TABLE 2.
Identification of Nodal and Gdf1 from purified material
Listed are normalized spectral counts of Nodal and Gdf1 identified after affinity purification of Nodal·Gdf1(His6) and Nodal·Gdf1(HA) using a nickel column. Fold, -fold change between Gdf1(HA) and Gdf1(His6). All other proteins did not show a -fold change higher than 1 or more than 3 spectral counts. Mature and pro-Nodal are found in bands 1 and 3, respectively. Mature and pro-Gdf1 are found in bands 2 and 3, respectively.
