Abcam’s multiplex immunoassays combine Firefly hydrogel technology with high-performance antibodies to simultaneously measure up to 75 different proteins in only 12.5 µL of sample. With sensitivity below 1 picogram/mL, the assay can provide multiplex data within hours, even in complex matrices with low target concentrations. Unlike many other multiplex assays that are bead-based, these assays can be run on most common flow cytometers, deliver 4–5 logs of linear dynamic range, and include free, easy-to-use analysis software. Additionally, researchers can choose from a growing menu of analytes to create a customized, ready-to-use panel to analyze complex inflammatory responses to diseases or treatments. Thanks to shared antibody pairs, users can seamlessly switch between Abcam’s 90-minute SimpleStep ELISA assays and multiplex immunoassays while maintaining high correlation. For even more flexibility, Abcam offers its multiplex immunoassays as both a convenient service and as kits for researchers to employ in their own labs.
