Endotoxin:
< 0.1 EU/μg of the protein by LAL method.
Purity:
≥ 90 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized recombinant Human IL22 at 2 μg/mL (100 μL/well) can bind recombinant Human IL22BP, the EC 50 of Human IL22BP is 10.78 ng/mL.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Interleukin 22 binding protein (IL-22BP), also known as CRF2-10, CRF2-X, and IL-22RA2, is a 35-45 kDa secreted glycoprotein in the type II cytokine receptor family (CRF). IL-22BP specifically binds to and inhibits interleukin 22 activity by blocking the interaction of interleukin 22 with its cell surface receptor.IL-22BP is produced by dendritic cells (DC), epithelial cells, activated B cells, and activated monocytes. It is constitutively expressed by DC but is down-regulated during local inflammation and in response to tissue damage. IL-22BP is critical for limiting IL-22 induced epithelial cell proliferation during wound healing, and its deficiency can enable uncontrolled proliferation and enhance tumor development.
Recombinant Human IL-22RA2/IL22BP Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
Immobilized recombinant Human IL22 at 2μg/mL (100μL/well) can bind recombinant Human IL22BP, the EC50 of Human IL22BP is 10.78 ng/mL.
