    • 特異性

      This antibody is used in our Rat IL-1beta EDK and was tested against the following rat growth factors at 50ng/ml to determine if there was any cross reactivity: GM-CSF, IL1alpha, IL-2, IL-4, IL-10, SCF, & TNFalpha. No significant cross reactivity was detected. The antibody has not been tested against endogenous IL1beta, only recombinant protein and we cannot guarantee it will detect endogenous protein.

    ターゲット情報

    • 機能

      Potent proinflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells.

    • 組織特異性

      Expressed in activated monocytes/macrophages (at protein level).

    • 配列類似性

      Belongs to the IL-1 family.

    • 翻訳後修飾

      Activation of the IL1B precursor involves a CASP1-catalyzed proteolytic cleavage. Processing and secretion are temporarily associated.

    • 細胞内局在

      Cytoplasm, cytosol. Lysosome. Secreted, exosome. Cytoplasmic vesicle, autophagosome. Secreted. The precursor is cytosolic. In response to inflammasome-activating signals, such as ATP for NLRP3 inflammasome or bacterial flagellin for NLRC4 inflammasome, cleaved and secreted. IL1B lacks any known signal sequence and the pathway(s) of its secretion is(are) not yet fully understood (PubMed:24201029). On the basis of experimental results, several unconventional secretion mechanisms have been proposed. 1. Secretion via secretory lysosomes: a fraction of CASP1 and IL1B precursor may be incorporated, by a yet undefined mechanism, into secretory lysosomes that undergo Ca(2+)-dependent exocytosis with release of mature IL1B (PubMed:15192144). 2. Secretory autophagy: IL1B-containing autophagosomes may fuse with endosomes or multivesicular bodies (MVBs) and then merge with the plasma membrane releasing soluble IL1B or IL1B-containing exosomes (PubMed:24201029). However, autophagy impacts IL1B production at several levels and its role in secretion is still controversial. 3. Secretion via exosomes: ATP-activation of P2RX7 leads to the formation of MVBs containing exosomes with entrapped IL1B, CASP1 and other inflammasome components. These MVBs undergo exocytosis with the release of exosomes. The release of soluble IL1B occurs after the lysis of exosome membranes (By similarity). 4. Secretion by microvesicle shedding: activation of the ATP receptor P2RX7 may induce an immediate shedding of membrane-derived microvesicles containing IL1B and possibly inflammasome components. The cytokine is then released in the extracellular compartment after microvesicle lysis (PubMed:11728343). 5. Release by translocation through permeabilized plasma membrane. This may occur in cells undergoing pyroptosis due to sustained activation of the inflammasome (By similarity). These mechanisms may not be not mutually exclusive.

    Question

    Dear technical team,

    Our customer would like to know the detailed information of ab9722 and ab9787immunogen.
    The customer has rat and mouse samples so, if it is possible, let me know the homology between two species.
    Thank you in advance.

    Best regards,

    Answer

    Thank you for your enquiry.

    As far as we are aware, ab9722 IL1 beta antibodyhas been tested and guaranteed in mouse but nottested in rat. the other ab9787IL1 beta antibody is tested and guaranteed for rat but not tested in mouse.

    As requested, I can confirm the following alignments:

    ab9722 Anti-IL1 beta antibody
    Already tested mouse.Alignment to rat: 89%

    ab9787 Anti-IL1 beta antibody
    Already tested rat.Alignment to mouse: 90%

    These alignments are high, so theoretically it is likely that ab9722 will detect in rat and that ab9787 will detect in mouse which I hope is good news for your customer. However, please note we are not able to guarantee this reactivity without further testing. If the customerwould like to test the antibody in this untested species, please contact me again by replying to this message prior to the purchase asthey may be eligible for our testing discount program.

    Otherwise, we like to encourage all of our customers to submit an Abreview via the online product datasheet. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as Amazon.com gift certificates.

    Question

    I have a follow-up question. Thank for the new lot of IL-1B - however, the new lot failed to fix our problem of having 1 band at 23 kDa. So we decided to run a loading control with pure IL-1beta we had in our lab. In the first 2 wells, I have 100 ng of IL-1B and 250 ng of IL-1B. In the third well I have 50 ng of IL-1B and 10 ug of a rat hippocampus sample that I have run before. In the fourth and fifth row I have 10 ug of rat hippocampus. We do see a band around 15-17 kDa, but there are several other bands in the wells with strictly IL-1B. Can you tell me what these other bands could be? I did my same protocol - with fresh beta mercaptoethanol and heated to 95 degrees for 5 minutes on a 4-20% gel and blocked in 5% filtered nonfat dry milk with the original antibody of IL-1B and with anti-rabbit secondary at 1:75,000. Please let me know if you need anymore information.

    Read More
    Answer

    Thank you for your reply.


    Unfortunately I am not sure what the identity of the extra bands might be. The protein you are using is not 100% pure so possibly other contaminants or strong multimers? It is reassuring that the antibody is recognizing the purified protein in your first few wells. It is very possible that the protein in the endogenous sample is simply running slightly higher due to a variety of factors, such as modifications, charge, etc.


    I do feel confident that the antibody is recognizing the correct protein. I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions.

    Answer

    Thank you for your reply.

    I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement with the order number XXX.

    To check the status of the order please contact our Customer Service team and reference this number.

    Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

    I wish you the best of luck with your research.

    Question

    Do you have any updates from the lab regarding the band detected by this antibody in my samples at 23kDa?

    Read More
    Answer

    Thank you for your patience as I have investigated this issue further with the laboratory.


    Based on your results and those obtained in our own laboratory it is not clear why this antibody is detecting a 23kDa band in your samples. I am happy to offer another lot or another antibody to this target as a replacement or instead a credit. Please let me know which you would prefer along with your previous order number.


    I look forward to your reply so that I may assist you further. Please do not hesitate to contact me if you have any additional questions.
