| Her peripheral blood smear, serum protein electrophoresis, and urine immunoelectrophoresis for Bence-Jones protein were normal. |
| The abnormal variant in both cases bound heparin normally but failed to bind dermatan sulfate as demonstrated by crossed immunoelectrophoresis. |
| The immunoglobulin type can be determined by immunoelectrophoresis or immunofixation electrophoresis. |
| Toxoplasmosis IgM and IgG antibodies, hepatitis B and C antibodies, serum immunoelectrophoresis, antidouble-stranded DNA, hemoglobin A1C, and antinuclear antibody were negative or normal. |
| These methods include enzyme inhibition assays,7,8 radial immunodiffusion,9 immunoelectrophoresis, and inhibition of immune hemolysis.10 Each of these methods has disadvantages. |
| Cross-over immunoelectrophoresis is the immunological method used in this analysis. |
