    Abstract:
    Human leukocyte-derived alpha interferon [HuIFN-alpha(Le)] has been purified and/or concentrated on Carboxymethyl derivatized Controlled Pore Glass (CML-CPG240) beads. These glass beads adsorb HuIFN-alpha(Le) efficiently at acid pH and at physiological ionic strengths. Elution of HuIFN-alpha(Le) may be accomplished by several methods. Using buffers at relatively high ionic strengths (approximately 0.6 M) and pH values ranging from 2.6 to 6.9 for elution, preparations with specific activities of 10(5)-10(6) IU/mg were obtained with approximately 90 percent recoveries. Alternatively, using elution buffers at the same high ionic strength and at pH values ranging from 7.0 to 8.0, five-fold or better concentration and complete recovery of crude HuIFN-alpha(Le) were achieved. The resulting preparations were suitable for direct application to an antibody affinity chromatography column.
