title: A new subfraction of routine fractionation.
abstract: The prothombin complex is adsorbed from plasma or cryoconcentrate supernatant onto DEAE-sephadex A50. The adsorbent is washed several times with 0.21 M NaCl. The first washing proved to be a new subfraction of routine fractionation suitable as starting material for the purification of several proteins such as C1-inactivator, N-carboxypeptidase, ceruloplasmin and kallikrein.
