Cytokines are essential molecules play crucial roles in many biological functions, including viral infection, inflammation, immunity, and hematopoiesis. Cytokines are produced by a variety of cell types in response to different stimuli. In addition, the expression of cytokine genes appears to be regulated by complex mechanism. Expression of one cytokine gene could be regulated by other cytokines. Dysregulation of cytokine gene expression may be caused by chromosomal alterations or by infection of viruses that induce activation or inactivation of the expression machinery. Therefore, profiling of these cytokines is critical to understanding these biological functions. Signosis' Mouse Cytokine ELISA Strip I Profiling Assay allows simultaneously profiling 8 cytokines. Each well of the strip is coated with a primary antibody against a specific cytokine and total 8 wells of a strip target 8 different cytokines. The difference of these proteins between two samples can be determined through data comparison.
