Bead-Based Immunoassays

BD™ Cytometric Bead Array (CBA) solutions measure a variety of soluble and intracellular proteins, including cytokines, chemokines, growth factors, and phosphorylated cell signaling proteins using flow cytometry. BD CBA solutions enable analysis of up to 30 proteins using just 25 to 50 μL of sample in comparison to other methods such as ELISA and Western blot, which enable only one protein to be analyzed per sample.

BD CBA solutions are available in preconfigured kits or in an open, configurable format for unique needs.

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.
