Abstract

Cytometric bead array (CBA) is a flow cytometry application that allows users to quantify multiple proteins simultaneously. Compared to other quantifier assays, as enzyme-linked immunosorbent assay (ELISA) and Western blot, CBA significantly reduces sample requirements and time to results. This technology allows for the design and creation of assays to measure a variety of analytes including inflammatory mediators, chemokines, immunoglobulin isotypes, intracellular signaling molecules, apoptotic mediators, adhesion molecules, and antibodies. Here we describe CBA steps to measure soluble cytokine levels in body fluids of infected patients by the protozoan Trypanosoma cruzi, morbidity known as Chagas disease.

Keywords: CBA; Cytokine measurement; Cytometric bead array; Flow cytometry.
