Abs for detection can be labeled with gold colloid clusters (GCCs). The Fc domain of the Abs binds to the clusters, and the Fab domain to the Ag on a nitrocellulose membrane or a microtiter plate as a support for dot-blotting. The signal of positive interaction between GCC-labeled Abs and its dotted Ag is detectable by the naked eye and can be quantified by comparison to a color scale prepared from a dilution series of known sample concentrations. The colored reaction product is stable for prolonged periods and does not fade, making this method a simple, fast, and convenient means for detection of Ag or Ab biorecognitions and an alternative to enzyme-linked immunosorbent assay. Several interactions between different Ags or Abs (eg, ß-lactoglobulin) and solutions avoiding gold colloidal cluster flocculation (eg, using protein G) were studied. CLISA was tested for other analytical purposes such as detection of IgEs in patients’ sera.Keywords: ELISA, allergen, patient sera, CLISA, immunoassay, ß-lactoglobulin Haifa Al-DubaiIrene LichtscheidlMartina Stroblet alDove Medical PressarticleMedical technologyR855-855.5Chemical technologyTP1-1185ENNanotechnology, Science and Applications, Vol 2010, Iss default, Pp 91-100 (2010) |
