IL36B, also known as Interleukin 36 beta and IL1F8, is a cytokine belonging to the IL-1 family. It is actively secreted and is found to form a cytokine gene cluster on chromosome 2 with eight other IL1 cytokines. IL36B signals through the IL1Rrp2/IL-36R receptor on dendritic cells which then activates NFkB and MAPK signalling pathways to create a pro-inflammatory response. It stimulates the production of mature adipocytes, and IL6 and IL8 synovial fibroblasts. It also induces expression of some antimicrobial peptides and matrix metalloproteases. It is highly expressed in psoriatic plaques, as part of the IL36 signalling system is found in many epithelial barriers.
Aliases- eta, Interleukin-1 eta, Interleukin-1 family member 8, Interleukin-1 homolog 2
Formulation- Lyophilized from a 0.2 µm filtered solution in PBS (with BSA as a carrier protein)
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles.
