TABLE 1.
Proteins identified after Nodal pulldown
Nodal protein was pulled down from mock or Nodal conditioned media in the presence of serum. Fold, -fold change between mock and Nodal conditioned medium (N/A indicates the protein was absent from mock). In bold are proteins specifically mentioned in the text. Other proteins were specifically enriched in the Nodal sample (phosphoglycerate kinase, periostin, and clathrin heavy chain). Shaded areas include proteins with a size corresponding to that of the isolated gel band. sub, subunit.
