Abstract
A universal antibody-mediated biosensor is provided that comprise a biosensor cell line stably expressing a novel chimeric fusion protein that can be used to detect target agents in a sample. The fusion protein has an extracellular antibody-binding domain that binds antibodies without regard to their binding specificity and a signaling domain that induces cellular activation upon antigen binding. Because the fusion protein binds to the Fc region of any antibody, it can serve as a universal pathway between extracellular signaling and intracellular activation. The biosensor can be used to detect the presence of selected antigens in a sample.
