IL-4 has been described as both an anti-inflammatory and a pro-inflammatory cytokine. It activates na?ve T cells to produce Th2 cells, stimulates activated B and T cell proliferation, and promotes the differentiation of B cells into plasma cells. It plays an important role in diminution of pathological inflammation via wound repair. IL-4 has been described to be involved in several inflammation-related diseases such as asthma, allergic skin inflammation, etc.
Recommended sample types are EDTA plasma and serum. A range of additional sample types are compatible with the technology (PEA), including citrate plasma, heparin plasma, cerebrospinal fluid, (CSF), tissue and cell lysates, fine needle biopsis, microdialysis fluid, cell culture media, dried blood spots, synovial fluid, saliva, plaque extract and microvesicles. Please note that protein expression levels are expected to vary in different sample types. Certain assays are differentially affected by interfering substances such as hemolysate.

Analytical Measuring Range
Please note: the technical data reported below refers to the measured value in the in vitro validation assays. The calibrator curves are generated during the assay validation process using recombinant antigens, with data presented as Normalized Protein eXpression (NPX) values plotted against protein concentration (in pg/mL). Please note that when analyzing biological samples the in vitro-generated curves presented here cannot be used to derive protein concentrations in pg/mL from the NPX values obtained. Olink Target 48 Cytokine delivers absolute protein concentrations directly using the calibrator system built into the system. For more information about NPX measurements, please view the FAQ.
Calibrator curve for validation data (generated in multiplex)
- Within run precision Coefficient of Variation (CV)
- Between run precision Coefficient of Variation (CV)
Precision (repeatability) is calculated on quantified data within the limit of quantification: LOQ, between lower limit of quantification (LLOQ) and upper limit of quantification (ULOQ).
