Revvity, 62HIL04PEH, HTRF Human IL-4 Detection Kit, 10,000 Assay Points

Overview
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 ir differentiation into plasma cells and ir class switch to immunoglobulin E, as well as promoting class II MHC expression. In immuno-oncology, IL4 induces 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 development of airway inflammation and allergic asthma.
Assessment of serum samples often requires enhanced sensitivity. In some cases, AlphaLISA assays may have sufficient sensitivity to enable detection of low levels of analytes in serum or plasma.
How it works
Assay principle
Cell supernatant, sample, or standard is dispensed directly into the assay plate for the detection by HTRF® reagents (384-well low-volume white plate or Revvity low-volume 96-well plate in 20 µl). The antibodies labeled with the HTRF donor and acceptor are pre-mixed and added in a single dispensing step, to further streamline the assay procedure. The assay can be run up to a 1536-well format by simply resizing each addition volume proportionally.

Assay data analysis
The 4 Parameter Logistic (4PL) curve is commonly recommended for fitting an ELISA standard curve. This regression enables the accurate measurement of an unknown sample across a wider range of concentrations than linear analysis, making it ideally suited to the analysis of biological systems like cytokine releases.
