  • Product overview

    Abcam’s IL-1 beta (Interleukin-1 beta) Rat ELISA (Enzyme-Linked Immunosorbent Assay) Kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of rat IL-1 beta in cell lysates and tissue lysates.

    This assay employs an antibody specific for rat IL-1 beta coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-1 beta present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-rat IL-1 beta antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and colour develops in proportion to the amount of IL-1 beta bound. The Stop Solution changes the colour from blue to yellow, and the intensity of the colour is measured at 450 nm.

  • Research areas
  • Function
    Produced 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 similarities
    Belongs to the IL-1 family.
  • Domain
    The similarity among the IL-1 precursors suggests that the amino ends of these proteins serve some as yet undefined function.
  • Cellular localization
    Secreted. 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.

I can suggest the following general tissue lysate preparation procedure to prepare samples for both the kits.

Tissue lyste samples can be prepared using most conventional methods, for example with RIPA or other formula...

Yes, that lysis buffer will be good, the 150 mM sodium chloride, 1.0% Triton X-100, 50 mM Tris pH 8.0.

Here are some general guidelines.

Avoid using >0.1% SDS or other strongly denaturing detergents. In general, non-ionic de...

Da die Tiere ja nur "durchgespült", aber nicht fixiert wurden, sollte dieses Kit mit den Leberlysaten funktionieren.

Vielen Dank für Ihre Anfrage.

Womit perfusieren Sie den die Tiere, PFA oder ein anderes Fixierungsmittel oder einfach nur PBS?

Ich freue mich auf Ihre Antwort.

Thank you for your enquiry. I can confirm that ab100767 IL1 beta Rat ELISA Kit would be the suitable kit to use with plasma samples. ab100768 IL1 beta Rat ELISA Kit is not designed for use with plasma samples. I hope this will be helpful to yo...
