| Immunofixation Electrophoresis An agarose gel electrophoresis first separates the proteins in a serum sample. Antiserum against the protein of interest is spread directly on the gel. The protein of interest precipitates in the gel matrix. After a wash step to remove other proteins, the precipitated protein is stained. This method is qualitative and is used to identify proteins found in multiple myeloma.Below is the immunofixation electrophoresis gel from a serum sample analyzed on SPIFE 3000, Helena Laboratories. After electrophoresis, the precipitated proteins are stained with Acid Violet, a stain developed and used by Helena Laboratories. The SP lane represents a routine serum protein electrophoresis of this specimen. On the next three protein separations, antiserum against IgG, IgA, and IgM were applied to the G, A, M lanes respectively. Antiserum to kappa light chain was added to the next protein separation and antiserum to lambda light chain to the last protein separation. | View Page |
| Electroimmunoassay Electrophoresis In electroimmunoassay electrophoresis, the antiserum is mixed in the gel during preparation. In the electrophoresis of the serum sample, the voltage drives the sample antigen into the antiserum creating a precipitin line in the shape of a rocket. This line is proportional to the concentration of the antigen, the protein to be detected. Each gel contains several serum samples, one antibody suspended in the gel, and standards of known concentration of antigen. Quantitation of the unknown antigen is derived from the height of the sample rockets compared to the height of the standard rockets. Electroimmunoassay electrophoresis is often referred to as rocket electrophoresis. | View Page |
