ELISA based free light chain assay for use with biological fluids

Utilising well characterised, highly specific, highly sensitive monoclonal antibodies, Seralite®– FLC ELISA (For Research Use Only) provides a robust and easy to use option for free light chain testing in biological fluids, utilising the same monoclonal antibodies used in our lateral flow method, Seralite®– FLC. The ELISA is a sequential sandwich assay format.

Seralite®– FLC ELISA is a 96 well format, 2 plate kit (1 x FLC-kappa, 1 x FLC-lambda) and can be used by either manual methods or using automated ELISA platforms.   Capture antibodies are supplied coated to 96 well (12 x 8) microplates with signal generated by antibodies labelled with horseradish peroxidase.
