1. Cytokines broadly defined as secreted cell cell signaling proteins distinct from classic hormones or neurotransmitters play important roles in inflammation innate immunity apoptosis angiogenesis cell growth and differentiation They are involved in most diseases including cancer obesity and inflammatory and cardiac diseases Simultaneous detection of multiple cytokines undoubtedly provides a powerful tool to study cytokines Regulation of cellular processes by cytokines is a complex dynamic process often involving multiple proteins Positive and negative feedback loops pleiotropic effects and redundant functions spatial and temporal expression of or synergistic interactions between multiple cytokines even regulation via release of soluble forms of membrane bound receptors all are common mechanisms modulating the effects of cytokine signaling As such unraveling the role of individual cytokines in physiologic or pathologic processes generally requires consideration and detection of multiple cytokines rather than of a single cytokine RayBio Human Cytokine Antibody Array G Series 5 RayBio G Series Cytokine Antibody Arrays have several advantages over detection of cytokines using single target ELISA 1 More Data Less Sample Antibody arrays provide high content screening using about the same sample volume as for ELISA 2 Global View_of Cytokine Expression Antibody array screening improves the chances for discoverin2.
