Application Abreviews Notes
ICC/IF Use at an assay dependent concentration.

IHC-P Use at an assay dependent concentration.
IHC-Fr Use at an assay dependent concentration.


  • FunctionProduced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.
  • Sequence similaritiesBelongs to the IL-1 family.
  • DomainThe similarity among the IL-1 precursors suggests that the amino ends of these proteins serve some as yet undefined function.
  • Cellular localizationSecreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.

  • ab8320 staining IL1 beta in lung inflammatory cells from Rhesus monkey by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde, permeabilized with Tween 20 and blocked with 10% serum for 2 hours at 21°C. Samples were incubated with primary antibody (1/25 in PBS + 10% serum + 1% Tween 20) for 18 hour at 4°C. An diluted Alexa Fluor®594-conjugated + 1.4nm Goat anti-mouse IgG polyclonal was used as the secondary antibody.

  • Immunohistochemical analysis of frozen Human skin tissue taken from patients with localized cutaneous leishmaniasis (A, C), diffuse cutaneous leishmaniasis (E). Normal tissue (G) was used as a negative control.

    IL1 beta was stained using ab8320 at 1/100 dilution for 1 hour at room temperature. ab94705 Mouse and Rabbit Specific HRP/AEC Detection IHC Kit was used to detect staining. Hematoxylin was used as a counterstain.

I am glad that the Rhesus tissue worked well! Unfortunately the homology for ab8320 with sheep is only 60%, to low for any reactivity. Another IL1-beta antibody, ab45692 does have 88% homology but has only been tested for Western Blot. Please let me kn...

Thank you very much for contacting us. To our knowledge, ab8320 has not been tested in rhesus monkey. The immunogen for this product is full length human IL1 beta, which has more than 90% homology with the Rhesus sequence. Based on this, I would predic...

Thank you for your enquiry and your interest in our products. Recommended positive control for this antibody can be activated human lymphocytes. We hope this will help.

Thank you for your email. I would suggest starting with a range of dilutions, 1:50, 1:100, 1:200, and then optimize from there based on your results. If you have any more questions, please contact us again.

Yes, we this antibody is routinely used in this application, although we have not tested it ourselves.
