Technical Data
EBV-Induced Gene 3 (EBI3, Interleukin-27 subunit beta, IL-27 subunit beta, IL-27B, Epstein-Barr virus-induced gene 3 protein)
Epstein-Barr virus-induced gene protein 3 (EBI3), also known as Interleukin-27 beta chain (IL27B) is a widely expressed homolog to the interleukin IL-12p40 subunit protein. It forms a heterodimer with either IL-12p35 or an IL-12p35 homologue, IL27-p28 (also called IL-28), to create a new cytokine (IL-27). IL-27 plays an important function in regulating the activity of B and T lymphocytes. It drives rapid clonal expansion of naive CD4(+) T-cells and strongly synergizes with IL-12 to trigger IFN-gamma production of naive CD4(+) T-cells. The human Ebi3 encodes a secreted glycoprotein that is expressed in the spleen and tonsils, and at high levels in full-term placenta.

Suitable for use in ELISA. Other applications not tested.

Recommended Dilution:
ELISA: 1:32000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
