HTRF HUMAN IL5 KIT - 500 PTS


品牌: Revvity









产品介绍
产品信息
Overview
IL5 is mainly produced by TH2 cells upon IL4 activation, but also by eosinophils and mast cells. IL5 promotes B cell growth and stimulates immunoglobulin secretion. It also induces eosinophil activation, proliferation, and differentiation.
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.
Revvity also worked with Myassays.com to help you in your data analysis.
