Sebia Hydragel Bence Jones
Sensitive immunological characterization of monoclonal free light chains
Test Presentation
Protein immunofixation is a well-established technique for the characterization of any suspected monoclonal component on serum or urine electrophoresis.
The HYDRAGEL BENCE JONES, when used on the HYDRASYS instrument, separates and characterizes Bence Jones proteins (Monoclonal Free Light Chains) or any other full monoclonal immunoglobulin, in human urine or serum.
The semi-automated HYDRASYS instrument offers sample application, electrophoretic migration, immunofixation and staining.
The sensitivity of the HYDRAGEL BENCE JONES kit allows the detection of very small monoclonal components.
A recent development on GELSCAN provides the ability to quantify the monoclonal protein from the ELP track.
TEST PRINCIPLE
The HYDRAGEL BENCE JONES assay is based on the principle of agarose gel electrophoresis immunofixation.
The HYDRASYS system is a semi-automated multi-parameter instrument.
The analytical steps include processing of the agarose gel in the following sequence:
- Sample application
- Electrophoretic migration
- Immunofixation
- Staining with acid violet dye
- Destaining
- Final drying
After separating serum or urine proteins according to their charge, the gel is incubated with different specific antisera targeted against:
- Heavy chains Gamma, Alpha, Mu (using the trivalent antiserum)
- Kappa (κ) and Lambda (λ) free and bound light chains
- Kappa (κ) and Lambda (λ) free light chains
The gel is subsequently washed in order to remove unbound antisera excess prior to the final staining step. The gels are then interpreted visually. Bands present on the immunological tracks indicate the presence of monoclonal immunoglobulin and/or free light chains.
PERFORMANCES
- Sensitivity:
- Internal sensitivity study demonstrated that a Bence Jones protein can be detected in a serum at a concentration:
- as low as 20 mg/L with anti-free & bound light chains antisera
- as low as 50 mg/L with anti-free light chains antisera.
- Internal sensitivity study demonstrated that a Bence Jones protein can be detected in a serum at a concentration:
- Full traceability and positive ID is obtained by connecting the HYDRASYS to the ASSIST pipetting station
