A-552 (A552) is a potent, small molecule antagonist of human IL-36γ, exhibits Ki of 31/54 nM in the human IL-36γ evoked CXCL1 release in human/mouse cellular assays.A-552 directly binds to human IL-36γ with IC50 of 67.6 nM measured by ITC, does not show affinity for either mouse IL-36γ, human IL-36α or IL-36β.A-552 attenuates human IL-36γ induced chemokine release in mouse plasma, and hIL-36γ induced inflammation in human 3D skin equivalents.A-552 is a novel first in class small molecule antagonist of the IL-36 signaling pathway that binds selective human IL-36γ and can dose-dependently inhibit IL-36γ induced production of proinflammatory cytokines from human and mouse cells.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
