Background of IL-18/IL-1F4
Interleukin-18 also known as IL18 is a protein which in humans is encoded by the IL18 gene. The protein encoded by this gene is a proinflammatory cytokine.IL-18 is a cytokine produced by macrophages and other cells that belongs to the IL-1 superfamily. IL-18 works by binding to the interleukin-18 receptor, and together with IL-12 it induces cell-mediated immunity following infection with microbial products like lipopolysaccharide (LPS). After stimulation with IL-18, natural killer (NK) cells and certain T cells release another important cytokine called interferon-gamma (IFN-gamma) or type II interferon that plays an important role in activating the macrophages or other cells.The combination of this cytokine and IL12 has been shown to inhibit IL4 dependent IgE and IgG1 production, and enhance IgG2a production in B cells. IL-18 binding protein (IL18BP) can specifically interact with this cytokine, and thus negatively regulate its biological activity. The human interleukin 18 gene IL18 maps to 11q22.2-q22.3, closely linked to the DRD2 gene locus and distinct from mapped IDDM loci.

Question
My colleagues were happy with the WB result of your anti-IL18 antibody. However we have seen positive staining in lower esophagus mucosa secreted. using this antibody. Is that expected? Could you tell me where is IL18 supposed to be expressed?
Verified Customer
Verified customer
Asked: 2020-02-21
Answer
Based on literature, lower esophagus mucosa does express IL18. Generally IL18 expresses in secreted. Regarding which tissues have IL18 expression, here are a few articles citing expression in various tissues:
Liver, Pubmed ID: 8666798, 15326478
Peripheral blood, Pubmed ID: 10653850
Urinary bladder, Pubmed ID: 15489334

Question
Can you help my question with product PA1342, anti-IL18 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?
Verified Customer
Verified customer
Asked: 2020-02-12
Answer
We suggest not storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PA1342 anti-IL18 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Question
Will PA1342 anti-IL18 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
J. Edwards
Verified customer
Asked: 2019-04-30
Answer
You can see on the product datasheet, PA1342 anti-IL18 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.
