  • Product overview

    Abcam’s IL-6 (Interleukin-6) Rat ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of rat IL-6 in serum, plasma or cell culture supernatants.

    This assay employs an antibody specific for Rat IL-6 coated on a 96- well plate. Standards and samples are pipetted into the wells and IL-6 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Rat IL-6 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 color develops in proportion to the amount of IL-6 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.


    Due to the relatively low abundance of IL-6 in normal rat serum and plasma, this kit may not be suitable for use with those sample types.

  • FunctionCytokine with a wide variety of biological functions. It is a potent inducer of the acute phase response. Plays an essential role in the final differentiation of B-cells into Ig-secreting cells Involved in lymphocyte and monocyte differentiation. It induces myeloma and plasmacytoma growth and induces nerve cells differentiation Acts on B-cells, T-cells, hepatocytes, hematopoietic progenitor cells and cells of the CNS. Also acts as a myokine. It is discharged into the bloodstream after muscle contraction and acts to increase the breakdown of fats and to improve insulin resistance.
  • Involvement in diseaseGenetic variations in IL6 are associated with susceptibility to rheumatoid arthritis systemic juvenile (RASJ) [MIM:604302]. An inflammatory articular disorder with systemic-onset beginning before the age of 16. It represents a subgroup of juvenile arthritis associated with severe extraarticular features and occasionally fatal complications. During active phases of the disorder, patients display a typical daily spiking fever, an evanescent macular rash, lymphadenopathy, hepatosplenomegaly, serositis, myalgia and arthritis.
    Note=A IL6 promoter polymorphism is associated with a lifetime risk of development of Kaposi sarcoma in HIV-infected men.

AbTrial test for rat lung tissue lysate samples

Inconclusive Excellent 5/5 (Ease of Use)
Tried rat lung lysate (in PBS) on kit ab100772, all the readings are either negative or below detection range. So this kit is not a good fit for tissue lysate

While serum and plasma samples maybe run undiluted, we do not usually recommend doing so. The reason is not because Assay Diluent A needs to be present in every sample but that testing undiluted serum/plasma...

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
