Precision
Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of bovine IL-4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regulates IL31RA expression in macrophages. Stimulates autophagy in dendritic cells by interfering with mTORC1 signaling and through the induction of RUFY4.
Gene References into Functions
  1. These results support pregnancy as type 2 immune response biased, with increases of IFN-gamma occurring after parturition and an increase in IL-4 production before calving. PMID: 23814356
  2. IL-4 may play a role in coordinating the adrenal response to inflammatory stress. PMID: 18055157
  3. T helper (Th) type 2 cell cytokine IL-4 modulates airway contraction by secreting matrix metalloproteinase-1 from the smooth muscle cells via phosphatidylinositol 3-kinase activation and changing cell-to-matrix interactions. PMID: 18322231
