NON-METAL COLLOIDAL PARTICLE IMMUNOASSAY

摘要

of the Invention A method of performing a diagnostic immunoassay utilizing a colloidal non-metal particles having conjugated thereto a binding component capable of specifically recognizing an analyte to be determined. After reaction of the sample and colloidal non-metal particles, the presence or amount of analyte/colloidal non-metal particle complexes are determined by optical analysis as a measure of the amount of analyte in the sample. The method can be utilized for the specific detection of numerous analytes and is sensitive and has a wide detection range.
