Six New Assays Added to Specialist Protein Analyzer

Six fully automated, easy-to-use assays were added to a specialist protein analyzer. They provide quantitative results to aid the assessment of a patient’s immune system.

The six assays include four cerebrospinal fluid (CSF) assays: immunoglobulin G (IgG), IgA, IgM, and albumin. Complement 1(C1) inactivator in plasma and serum, for the investigation of hereditary angioedema, and transferrin in serum, for estimation of iron deficiency anaemia, were also added to the analyzer menu.


These additions complement the panel of assays currently available on SPAplus including Hevylite immunoglobulin heavy chain/light chain assays, Freelite serum free light chain assays, and various complement assays.

Binding Site’s (Birmingham, United Kingdom) SPAplus specialist protein analyzer was designed to bring together instrument, reagents, and support as a package. A compact, turbidimetric platform, the fully automated SPAPLUS system enables laboratories to maintain the quality of results and high throughput required for specialized protein assays. It can be placed alongside the laboratory’s main-line analyzers or in other areas of the laboratory.

Preprogrammed protocols, developed and manufactured by Binding Site, provide sensitive and reproducible results that match or have greater sensitivity than nephelometry. The modular design with intuitive Windows based software makes the SPAplus very easy to use.

SPAplus has an expanding menu of diagnostic tests related to disease state management and clinical practice guidelines. More assays will be added during 2012.
