IL4 Chemi-Luminescent ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Interleukin 4 (IL4) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Interleukin 4 (IL4) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

B cell growth factor 1; B_cell stimulatory factor 1; B-cell stimulatory factor 1; BCGF1; BCGF-1; binetrakin; BSF1; BSF-1; IL-4; interleukin 4 variant 2; interleukin-4; lymphocyte stimulatory factor 1; pitrakinra.

Participates in at least several B-cell activation processes as well as of other cell types (PubMed:3016727) . 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 (By similarity) .

The microplate provided in this kit has been pre-coated with an antibody specific to Interleukin 4 (IL4) . Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Interleukin 4 (IL4) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Interleukin 4 (IL4) level in the sample or standard.
