Assays
Freelite comprises two new immunodiagnostic assays for accurate and rapid quantification of free kappa and free lambda light chain concentrations in serum.
Affinity purified polyclonal antibodies, reacting specifically with the free forms of kappa and lambda light chain, are precoated onto latex particles. These latex reagents are used to produce nephelometric and turbidimetric kits that are specific for free light chains. The greater sensitivity of these assays means that for the first time in routine practice, serum free light chains can be detected and quantitated down to normal levels. Assays are available on a wide range of automated platforms, ensuring accuracy and reduced hands on time.
