A "Mix and Read" Assay for Insulin Using Fluorometric Microvolume Assay Technology

摘要

We describe a novel, "mix and read" immunoassay for insulin in biological samples using FMAT. Current commercial assays for insulin require multiple washing steps and can be expensive. The insulin assay described is a simple two-step, time-saving assay and amenable to robotics. The linear response for the fluorometric signal is comparable to that observed using classical ELISA and RIA. A series of mouse plasma samples were tested for insulin levels and yielded results comparable to that measured using a commercial ELISA for insulin.
