Data Examples
Intracellular Staining by Flow Cytometry
Detection of IL‑22BP in Human PBMCs by Flow Cytometry. Human peripheral blood mononuclear cells (PBMCs) (A) untreated or (B) treated overnight with 250 ng/mL LPS were stained with Mouse Anti-Human IL‑22BP PE‑conjugated Monoclonal Antibody (Catalog # IC10871P) and Mouse Anti-Human CD14 APC‑conjugated Monoclonal Antibody (Catalog # FAB3832A). Quadrant markers were set based on control antibody staining (Catalog # IC0041P). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: IL-22BP

Interleukin 22 Binding Protein (IL-22BP), also known as Cytokine Receptor Family (CRF) 2‑10, CRF2-X, and IL-22 RA2, is a secreted glycoprotein belonging to the type II cytokine receptor family. It encodes a precursor protein of 231 amino acid (aa) residues with a 21 aa putative signal peptide and five potential N-linked glycosylation sites. IL-22BP lacks a transmembrane and cytoplasmic domain and is most closely related to the extracellular domains of IL-22 R (CRF2-9) and IL-20 R (CRF2-8), sharing 33% and 34% aa sequence identity, respectively. It also shares sequence homology with the extracellular domains of IL-10 R (29%), IL-10 R beta (30%), the IFN receptors (23-25%) and tissue factor (26%). IL-22BP antagonizes IL-22 activity by specifically binding IL-22 with high affinity and blocking its interaction with the cell surface IL-22 receptor heteromeric complex composed of IL-22 R and IL-20 R. IL-22BP is expressed in multiple tissues. The highest levels of expression are found in breast, lungs and colon. The major cell types producing IL-22BP are monocytes, activated B cells and epithelial cells (1). IL-22BP is constitutively expressed by a subset of conventional dendritic cells (2). IL-22BP is regulated by the inflammasome and it has been suggested to modulate tumorigenesis in the intestine (3).
