Purity
>97% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The ED50 as determined by inducing IL-6 secretion in murine NIH/3T3 cells is less than 10ng/ml, corresponding to a specific activity of >1.0×105IU/mg.
Physical Appearance
Sterile Filtered lyophilized (freeze-dried) liquid-like powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, 5% trehalose.
Endotoxin
Less than 1EU/μg of rMuIL-36β, 153a.a. as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.
Background
Interleukin-36 is a pro-inflammatory cytokine which plays an important role in the pathophysiology of several diseases. IL-36α, IL-36β, and IL-36γ (formerly IL-1F6, IL-1F8, and IL-1F9) are IL-1 family members that signal through the IL-1 receptor family members IL-1Rrp2 (IL-1RL2) and IL-1RAcP. IL-36 beta is reported to be expressed at higher levels in psoriatic plaques than in symptomless psoriatic skin or healthy control skin and it can stimulate production of interleukin-6 and interleukin-8 in synovial fibrobasts, articular chondrocytes and mature adipocytes. IL-36 beta has two isoforms. IL-36β2 contains one potential N-linked glycosylation site in its C-terminus, while IL -36β isoform 1 lacks potential N-linked glycosylation sites and four of the conserved β-strands. Within the IL-1 family, IL-36β/IL-1F8 shares 30%, 32%, 37%, 46%, 34%, 45% and 28% aa sequence identity with IL-1 ra, IL-1β, IL-36Ra/IL-1F5, IL-36α/IL-1F6, IL-37/IL-1F7, IL-36γ/IL-1F9 and IL-1F10, respectively.
