In this paper, we present the demonstration of a size-encoded bead-based multiplexed immunoassay with image cytometric decoding and readout. Antibodies were immobilized on polystyrene microspheres by physical adsorption and employed for the demonstration of this duplexed immunoassay. First, we carried out a duplexed immunoassay with a mouse and rat IgG detection system and discussed the problem of cross-reactivity inherent to these immunoreaction systems. We then carried out a duplexed immunoassay with a mouse IgG and human albumin detection system, which was less cross-reactive. We subsequently demonstrated the application of size-encoded image cytometric decoding and the detection of mouse IgG and human albumin using this duplexed immunoassay system.
