Cisbio

Detection of human IL4 using HTRF (an alternative to ELISA) Cisbio kit 62HIL04PEG.

IL4 is expressed by T cells, NK cells and mast cells, and is an important regulator of humoral and adaptative immunity. It stimulates activated B cells, and induces their differentiation into plasma cells and their class switch to immunoglobulin E, as well as promoting class II MHC expression. In immuno-oncology, IL4 induces the differentiation of naïve T cells into TH2 cells, which in turn produce IL4 and thus create a positive feedback loop. IL4 is also involved in the development of airway inflammation and allergic asthma. Cisbio's Human IL4 kit is a homogeneous, add and read assay to measure IL4 secretion in supernatant. It offers a fast, efficient alternative to ELISA.

This data analysis tool performs quantitative analysis of samples using a 1/y² weighted Four Parameter Logistic (4PL) curve fit. Provide your ratio calculated measurement data (665nm/620nm). Calculations are performed as follows:

1. Delta Ratio is computed for each sample using the zero standard (Zero).

2. The standard data points (Concentration vs. Delta Ratio) are plotted and the curve is fitted through the points. The concentrations of the samples are determined from the fit with any specified dilution factors applied.

3. The %CV and Standard Deviation are calculated for each replicated sample.
