  • 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 serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for 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.

Perdona por la espera.
Es muy posible que el motivo de la baja absorbancia observada en las placas se deba a la perdida de actividad de alguno de los componentes del kit, debido a su degradación por haberse mantenido durante tantos meses a 4C. Read More
