Cytokine Detection

Cytokine Detection Cytokine detection is important when studying cellular communication, immune response, inflammation and hematopoiesis. Cytokines, which are small signaling proteins, have historicaly have been grouped based on criteria such as protein structure and function. These subgroups include interleukins (secreted by leukocytes), chemokines (chemotaxis-inducing), interferons (antiviral activity) and tumor necrosis factors (containing the TNF structural domain). Based on their role in controlling inflammation, they are also subdivided as either proinflammatory and anti-inflammatory cytokines. When investigating cytokines, an immunodetection approach is common in which cytokine-specific antibodies are used in staining, ELISA, or other types of immunoassay. Intracellular cytokine detection can also be accomplished by flow cytometry after labeling the interior of cells antibodies with fluorescent reporters. Important features to look for in cytokine assay kits are sensitivity, broad dynamic range, and quality of the antibody pairs’ affinity and specificity.
