Comments:

NOTE:  Many autoimmune disorders, chronic infections, and malignancies 
are associated with circulating immune complexes. Quantitation of 
immune complexes assists in staging immunologic disorders. Immune 
complexes bind to Raji cells via their complement receptors. The 
immunoglobulin portion of the immune complex is then detected by flow 
cytometry with anti-human IgG-FITC.

Flow Cytometry
