title: [Preparation and application of monoclonal antibodies to recombinant human IFN alpha].
abstract: OBJECTIVE
  To prepare and apply monoclonal antibodies (McAb) against recombinant human interferon alpha (rHu IFN-alpha).
  
  
  METHODS
  Five cell lines (2E9, 4G1, 2A7, 2C9, 4G10) secreting McAbs against rHu IFN-alpha were established by hybridoma technique.
  
  
  RESULTS
  All the cell lines secreted monoclonal antibodies stably. Functions of secreting antibodies of the five cell lines lasted for 6 months in BALB/c mice and 8 months in cell culture. The specificity of antibody was constant. The Ig subclasses of the McAbs were IgG1. Anti-IFN McAb affinity purification column was prepared by coupling the anti IFN-alpha McAb to Sepharose 4B. The combining rate reached was higher than 95%.
  
  
  CONCLUSIONS
  The highest purification efficiency was obtained by using 4G10 column.
