IL-21 is a pro-inflammatory cytokine and is produced by several T cells, including CD4+, T follicular helper and T-helper 17 cells.

Overproduction of IL-21 occurs in many inflammatory diseases such as rheumatoid arthritis, SLE and organ transplantation. 

The level of IL-21 in supernatant, serum or plasma can be determined by ELISA. The IL-21 capacity of T cells or the frequency of IL-21 producing cells can be determined by ELISPOT assay.

U-CyTech's human IL-21 ELISA or IL-21 ELISPOT kit allows you to measure the important IL-21 cytokine.

We are pleased to offer you a 20% discount on our IL-21 kits.
