Interleukin-36β (IL36 beta) is a pro-inflammatory cytokine that plays an important role in the pathophysiology of several diseases. IL36B has been reported to be expressed at higher levels in psoriatic plaques rather than symptomless psoriatic skin or healthy control skin. Furthermore, IL36B can stimulate production of IL6 and IL8 in synovial fibroblasts, articular chondrocytes and mature adipocytes. Human IL36B shares low sequence identity with IL1B, IL36RN, IL36A and IL36G.

Endotoxin Test:
<0.1 EU per 1 μg of the protein by the LAL method. Activity:
Measure by its ability to induce IL-8 secretion in human PBMCs. The ED₅₀ for this effect is <0.2 ng/mL. Purity:
>98% as determined by SDS-PAGE. Ni-NTA chromatography

Formulation:
The protein was lyophilized from a solution containing 1X PBS, pH 7.4.

Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Storage:
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.

Note:
Please use within one month after protein reconstitution.
