Applications

Our Abpromise guarantee covers the use of ab110535 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Neutralising Use a concentration of 0.2 - 0.4 µg/ml. To yield one-half maximal inhibition [ND50] of the biological activity of Human IL33 (1.0 ng/ml).
WB Use a concentration of 0.1 - 0.2 µg/ml. Predicted molecular weight: 30 kDa. The detection limit for recombinant hIL33 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
Indirect ELISA Use a concentration of 0.5 - 2 µg/ml. ab110535, in conjunction with compatible secondary reagents, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human IL33.
Sandwich ELISA Use a concentration of 0.5 - 2 µg/ml. Can be paired for Sandwich ELISA with Rabbit polyclonal to IL33 (Biotin) (ab84249). ab110535, in conjunction with ab84249 as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human IL33.

Target

  • FunctionCytokine that binds to and signals through the IL1RL1/ST2 receptor which in turn activates NF-kappa-B and MAPK signaling pathways in target cells (PubMed:16286016). Involved in the maturation of Th2 cells inducing the secretion of T-helper type 2-associated cytokines. Also involved in activation of mast cells, basophils, eosinophils and natural killer cells. Acts as a chemoattractant for Th2 cells, and may function as an "alarmin", that amplifies immune responses during tissue injury (PubMed:17853410, PubMed:18836528).
    In quiescent endothelia the uncleaved form is constitutively and abundantly expressed, and acts as a chromatin-associated nuclear factor with transcriptional repressor properties, it may sequester nuclear NF-kappaB/RELA, lowering expression of its targets (PubMed:21734074). This form is rapidely lost upon angiogenic or proinflammatory activation (PubMed:18787100).
  • Tissue specificityExpressed at high level in high endothelial venules found in tonsils, Peyer patches and mesenteric lymph nodes. Almost undetectable in placenta.
  • Sequence similaritiesBelongs to the IL-1 family. Highly divergent.
  • DomainThe homeodomain-like HTH domain mediates nuclear localization and heterochromatin association.
  • Post-translational
    modifications
    The full length protein can be released from cells and is able to signal via the IL1RL1/ST2 receptor. However, proteolytic processing by CSTG/cathepsin G and ELANE/neutrophil elastase produces C-terminal peptides that are more active than the unprocessed full length protein. May also be proteolytically processed by calpains (PubMed:19596270). Proteolytic cleavage mediated by apoptotic caspases including CASP3 and CASP7 results in IL33 inactivation (PubMed:19559631). In vitro proteolytic cleavage by CASP1 was reported (PubMed:16286016) but could not be confirmed in vivo (PubMed:19465481) suggesting that IL33 is probably not a direct substrate for that caspase.
  • Cellular localizationNucleus. Chromosome. Cytoplasmic vesicle, secretory vesicle. Secreted. Associates with heterochromatin and mitotic chromosomes. Translocation from the nucleus occurs upon biomechanical strain, depends on an intact microtubule network, and is ATP-dependent.
