线性度：

To assess the linearity of the assay, samples were spiked with high concentrations of rabbit IL-4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	86
	Range %	80-92
1:2	Average %	100
	Range %	91-105
1:4	Average %	97
	Range %	92-105
1:8	Average %	94
	Range %	86-98

回收率：

The recovery of rabbit IL-4 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	93	89-98
EDTA plasma (n=4)	95	90-100

标准曲线：

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

功能：

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.
