IL-33 is a nuclear cytokine from the IL-1 family constitutively expressed in epithelial barrier tissues and lymphoid organs, which plays important roles in type-2 innate immunity and human asthma. Recent studies indicate that IL-33 induces production of large amounts of IL-5 and IL-13 by group 2 innate lymphoid cells (ILC2s), for initiation of allergic inflammation shortly after exposure to allergens or infection with parasites or viruses. IL-33 appears to function as an alarmin (alarm signal) rapidly released from producing cells upon cellular damage or cellular stress.

Reconstitute at 0.1-1 mg/ml according to the size in ultrapure water after rapid centrifugation.

· 12 months from date of receipt, lyophilized powder stored at -20 to -80℃.
· 3 months, -20 to -80℃ under sterile conditions after reconstitution.
· 1 week, 2 to 8℃ under sterile conditions after reconstitution.
· Please avoid repeated freeze-thaw cycles.
