Serum protein electrophoresis (SPE) can be used for the initial screening of serum (or concentrated urine) for monoclonal immunoglobulins and light chains (Bence Jones protein), aiding in the diagnosis of monoclonal gammopathies.

However, optimal detection of paraproteins is achieved by screening serum samples both with SPE or CZE (Capillary Zone Electrophoresis) and Freelite serum free light chain assays.

Samples exhibiting either abnormal bands by SPE or abnormal levels of free kappa, free lambda or κ/λ ratio by Freelite should be further investigated by immunofixation and quantitation of other specific serum proteins.

Each SPE kit contains reagents sufficient for 100 tests. Each of the 10 gels can be used to run 10 samples.

Electrophoresis and Immunofixation

immunoglobulins on a Minifix gel

Immunofixation electrophoresis (IFE) is a two-stage process combining agarose gel electrophoresis with immuno-precipitation. It has replaced IEP (immunoelectrophoresis) as the method of choice for identification and characterisation of monoclonal immunoglobulins in serum, urine and cerebrospinal fluid. IFE allows ease of interpretation, fast results (less than 2 hours) and has good sensitivity.

IFE Components

Individual vials of antisera are available for customers who prefer to purchase reagents separately. These products are optimised for use with the IFE (XK002) gel kit which contains the same components as a standard IFE kit but without antisera.
