Background of IL-33

Interleukin 33 (IL-33) is a protein that in humans is encoded by the IL33 gene. The protein encoded by this gene is a cytokine that binds to the IL1RL1/ST2 receptor. The encoded protein is involved in the maturation of Th2 cells and the activation of mast cells, basophils, eosinophils and natural killer cells. Several transcript variants encoding different isoforms have been found for this gene.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

4 Customer Q&As for Anti-IL33 Antibody Picoband™


Our team were happy with the WB result of your anti-IL33 antibody. However we have seen positive staining in left coronary artery nucleus using this antibody. Is that expected? Could you tell me where is IL33 supposed to be expressed?

A. Johnson

Verified customer

Asked: 2017-04-07


From what I have seen in literature, left coronary artery does express IL33. Generally IL33 expresses in nucleus. Regarding which tissues have IL33 expression, here are a few articles citing expression in various tissues:
Adrenal gland, and Trachea, Pubmed ID: 14702039
Brain, Pubmed ID: 15489334
Endothelial cell, Pubmed ID: 12819012

We are currently using anti-IL33 antibody A00113 for human tissue, and we are content with the ELISA results. The species of reactivity given in the datasheet says human. Is it likely that the antibody can work on canine tissues as well?

B. Yang

Verified customer

Asked: 2015-11-23


The anti-IL33 antibody (A00113) has not been tested for cross reactivity specifically with canine tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in canine you can get your next antibody for free. Please contact me if I can help you with anything.

We have tried in the past anti-IL33 antibody for WB on brain in a previous experiment. I am using human, and I plan to use the antibody for ELISA next. I am interested in examining brain as well as endothelial cell in our next experiment. Could give a recommendation on which antibody would work the best for ELISA?

T. Jha

Verified customer

Asked: 2015-04-23


I have checked the website and datasheets of our anti-IL33 antibody and it appears that A00113 has been validated on human in both WB and ELISA. Thus A00113 should work for your application. Our Boster satisfaction guarantee will cover this product for ELISA in human even if the specific tissue type has not been validated. We do have a comprehensive range of products for ELISA detection and you can check out our website to find out more information about them.
