Bead-Based Immunoassays

Multiplexed quantitation and detection

BD™ Cytometric Bead Array (CBA) is a flow cytometry application that allows users to quantify multiple proteins simultaneously. The BD CBA system uses the broad dynamic range of fluorescence detection offered by flow cytometry and antibody-coated beads to efficiently capture analytes. Each bead in the array has a unique fluorescence intensity so that beads can be mixed and run simultaneously in a single tube. This method significantly reduces sample requirements and time to results in comparison with traditional ELISA and Western blot techniques.

BD CBA Flex Sets provide an open and configurable method of detection, so that researchers can build their own multiplexes for protein quantitation as low as 10 pg/mL.

BD CBA Enhanced Sensitivity Flex Sets are capable of detecting cytokine concentrations as low as 0.274 pg/mL.

BD CBA Kits are preconfigured for achieving consistent results for routine panels.
