Webdifferent target molecule. Bio-Plex cytokine assays are designed in a capture sandwich immunoassay format. Antibody specifically directed against the cytokine of interest is covalently coupled to color-coded 5.6 µm polystyrene beads. The antibody-coupled beads are allowed to react with a sample containing an unknown amount of cytokine, WebJan 9, 2015 · Apoptotic cells secrete cytokines that suppress inflammation while promoting phagocytosis. Increased numbers of apoptotic cells in PBMC may modulate T cell functions in antigen-triggered T cell assays. We assessed the effect of apoptotic bystander cells on a T cell ELISPOT assay by selectively inducing B cell apoptosis using α-CD20 mAbs.
