Multiplex Immunoassay Service


Cytometric Bead Array (CBA) Multiplex Assay Kit

CBA Multiplex Detection (Cytometric Bead Array) is a flow cytometry–based method for simultaneous quantification of multiple soluble proteins. Through measuring bead fluorescence and PE fluorescence, multiple cytokines or chemokines can be quantified in a single sample.


Wan Care ELISA services include reliable execution of CBA commercial kits and custom assay development for unique projects. We use reliable machine and softwares to address your project needs.


Why choose multiplex immunoassay?


Multiplex in One Well

Detect up to 15 analytes simultaneously, reducing sample use.

High Sensitivity & Wide Range

Sensitivity down to 0.1 pg/mL with a four-log dynamic range for accurate quantification of low- and high-abundance targets.

Accurate Results

Meticulous assay execution and highly sensitive instrumentation enable accurate multiplex immunoassay performance.


Data Demonstration

After sample pretreatment using the assay kit, samples are analyzed on a flow cytometer. By optimizing acquisition parameters and identifying bead subpopulations with minimal overlap, accurate simultaneous quantification of multiple targets can be achieved.
