SUN, T. ... et al, 1999. Isolation of human fibrinogen by axial and radial flow chromatography from Nitschmann fraction I. Biotechnology Techniques, 13 (12), pp.831-835
An axial column (3×2.6 cm) and a radial flow column (3.5×5 cm) packed with DEAE Sepharose Fast Flow media had been evaluated for the separation of human fibrinogen. Nitschmann fraction I dissolved in buffered saline (0.015 M NaCl buffered with 0.06 M Tris/HCl to pH 7.5) was the starting material. Under radial flow conditions, sample flow up to 15 ml min−1 (i.e., 18 bed volumes h−1) was achieved. The operating pressures were below 0.2 MPa, even though the elution velocity was 30 ml min−1 (i.e., 36 bed volumes h−1).
