IL-33 (Human) ELISA Kit - E4888

E4888 | IL-33 (Human) ELISA Kit DataSheet

Interleukin-33 (IL-33) belongs to the family of IL-1 cytokines. It is constitutively expressed at increased levels in the nuclei of multiple cell types such as glial, endothelial, smooth muscle, and immune cells. When present in the nucleus, IL-33 functions as a transcriptional repressor, whereas extracellularly, it acts as a traditional cytokine by inducing Th2-type immunity. It also acts as an ‘alarmin’ for the immune system when released by damaged tissues or cell necrosis. Expression of IL-33 is upregulated in cancer and immune-related diseases such as rheumatoid arthritis, asthma, psoriatic arthritis. IL-33 also plays a protective role in cardiovascular and neurodegenerative diseases. Hence, IL-33 could potentially serve as an efficient biomarker for human diseases. ’s IL-33 (Human) ELISA kit is based on the Sandwich ELISA principle to quantitatively measure the amount of IL-33 in human serum, plasma, and other biological fluids. Test samples, Standards, and Biotinylated Detection antibody are added to the wells pre-coated with capture antibody and subsequently washed with Wash Buffer. The HRP-Streptavidin is added and any unattached conjugates are washed off using Wash Buffer. The HRP enzymatic reaction is detected by the addition of TMB-substrate. Finally, the reaction is terminated with an acidic stop solution. The color developed is proportional to the amount of IL-33 in the sample or standard.
