Human IL-21(Interleukin 21) ELISA Kit

The Human IL-21(Interleukin 21) ELISA Kit is a highly reliable and sensitive assay designed for the quantitative detection of human IL-21 in serum, plasma, and cell culture supernatants. This kit is based on the sandwich enzyme-linked immunosorbent assay (ELISA) principle, which utilizes a monoclonal antibody specific to human IL-21 to capture the target protein. The captured protein is then detected using a biotinylated polyclonal antibody and streptavidin-HRP conjugate. The assay is performed in a 96-well microplate format, and the results are read using a microplate reader at 450 nm.

The Human IL-21 ELISA Kit is a valuable tool for researchers studying the role of IL-21 in various biological processes, including immune regulation, inflammation, and cancer. The kit offers high sensitivity, specificity, and reproducibility, making it an ideal choice for both basic research and clinical applications. The kit includes all necessary reagents and controls, and the protocol is easy to follow, allowing for quick and accurate results. Overall, the Human IL-21 ELISA Kit is a reliable and efficient tool for the detection and quantification of human IL-21, providing researchers with valuable insights into the role of this cytokine in human health and disease.
