Sigma-Aldrich Anti-Il-22 Clone 1H8-L1 Zoomab Rb

Interleukin-22 (UniProt: Q9GZX6; also known as Cytokine Zcyto18, IL-10-related T-cell-derived-inducible factor (IL-TIF)) is encoded by the IL22 (also known as ILTIF, ZCYTO18, UNQ3099/PRO10096) gene (Gene ID: 50616) in human. IL-22 is an -helical cytokine that contributes to the inflammatory response in vivo. It is a secretory protein that is synthesized with a signal peptide (aa 1-33), which is subsequently cleaved off to produce the mature protein. It is immediately produced to initiate immune response against several tissue impairments. It is considered as a fundamental mediator in inflammation, mucous production, protective role against pathogens, wound healing, and tissue regeneration. It is produced by several populations of immune cells, including macrophages, β T cells classes Th1, Th22, and Th17 cells at the site of inflammation. It is shown to up-regulate a number of mucus associated genes, such as MUC1, MUC3, MUC10, and MUC13 in colonic and tracheal epithelial cells. Along with IL-17A, it also produces pulmonary mucus as a control against Gram negative pathogens. Its biological activity is initiated by binding to a cell-surface complex composed of IL-22R1 and IL-10R2 receptor chains and further regulated by interactions with a soluble binding protein (IL-22BP). IL-22 is shown to have a very high affinity for binding to IL-22BP, which acts as a natural antagonist of IL-22. IL-22BP binding occurs at specific sites on IL-22 that are also utilized by IL-22R1. (Ref.: Arshad, T., et al. (2020). Front. Immunol. 11; 2148). This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1H8-L1 is a ZooMAb^® rabbit recombinant monoclonal antibody that detects IL-22. It targets an epitope within 21 amino acids from the C-terminal half.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
