Validation:

Recombinant Protein Test (Figure 2) shows that anti-EBI-3 antibody (4967) detects human recombinant IL-17 (IL-17A + IL-17B) protein that contains the amino acids of 4967 antigenic peptide.

Isoform: Human EBI-3 has only 1 isoform (229aa, 25kD) . Mouse EBI-3 has one isoform (228aa, 25kD) and rat EBI-3 also has one isoform (228aa, 25kD) . 4967 can detect human EBI-3 but cannot detect mouse and rat EBI-3.

BACKGROUND: EBI3 Antibody: EBI3 is a subunit in two distinct heterodimeric cytokines: interleukin-27 (IL-27) and IL-35. Like interleukin-23 (IL-23) , IL-27 is a recently discovered member of the IL-6/IL-12 family of proinflammatory and immunoregulatory cytokines. It exists as a heterodimer composed of the p40-related protein EBI3 and an IL-12 p35-related protein termed p28. IL-27 is produced after activation by antigen-presenting cells and induces proliferation of naïve but not memory CD4+ T-cells. It acts by binding to its receptor WSX-1 (also known as TCCR) and gp130 which results in the activation of a Jak/STAT signaling cascade, suggesting the IL-27 is involved in the regulation of immune processes. It has been suggested that IL-27 can also be used as a therapeutic agent against cancer as it can also induce tumor-specific anti-tumor activity mediated through CD8+ T-cells, IFN-gamma, and T-bet. IL-35 is composed of EBI3 and the p35 subunit of IL-12 and has been reported to have therapeutic effects against collagen-induced arthritis by expanding the population of regulatory T cells and suppressing Th17 cells. At least two isoform of EBI3 are known to exist.
