Binding Site is a Special Protein company committed to the research, development, manufacture, and distribution of innovative immunodiagnostic assays for the global laboratory market. With extensive expertise in antibody specificity technology, Binding Site gives clinicians and
laboratory staff the tools to significantly improve diagnosis and management of patients.

Innovative Immunodiagnostic Assays from Binding Site

Freelite® is a well established serum assay used for the diagnosis and monitoring of Multiple Myeloma, a cancer of cells in the bone marrow.

Freelite comprises two immunodiagnostic assays for accurate and rapid quantification of free k (kappa) and free l (lambda) immunoglobulin light chain concentrations. These assays can be performed on a significant number of automated platforms giving a sensitivity, accessibility, and consistency never before achievable. Freelite has allowed significant improvements in both laboratory and clinical practice for the detection and monitoring of Multiple Myeloma.

Hevylite® is a unique immunoassay panel designed for identification and quantification of immunoglobulin heavy and light chain isotypes. Like Freelite, Hevylite is used in monitoring patients with Multiple Myeloma.

Freelite and Hevylite provide complementary insights into Multiple Myeloma management.

Binding Site is a market leader in the development of products for the investigation of immune status including immunodeficiency diseases. Our current range of specialized products includes assays for:
●Quantifying immunoglobulins & subclasses
●Measuring complement proteins

Optimized Instrumentation and Assays
We recently launched our newest analyzer, expanding our instrumentation line with the latest innovation in special protein testing. With its custom design and powerful technology, Optilite® is the future of special protein testing. Optilite joins our existing Special Protein Analyzer, the
SPAPLUS®. Both systems have been developed exclusively for Binding Site Special Protein Assays, bringing harmony to assay and analyzer alike. These dedicated systems, along with Binding Site’s exceptional support, ensure optimal assay performance, system throughput, and user experience.
