  • Product overview

    Abcam’s TSLP Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed the quantitative measurement of Human TSLP in serum, plasma and cell culture supernatants.

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

    Get higher sensitivity in only 90 minutes with Human TSLP ELISA Kit (ab192149) from our SimpleStep ELISA® range.

  • Research areas

  • Relevance

    The TSLP gene encodes a hemopoietic cytokine proposed to signal through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. This mainly impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes and enhances the maturation of CD11c(+) dendritic cells. The protein promotes T helper type 2 (TH2) cell responses that are associated with immunity in various inflammatory diseases, including asthma, chronic obstructive pulmonary disease and allergic inflammation. The protein is therefore considered a potential therapeutic target for the treatment of these diseases. Alternative splicing of this gene results in multiple transcript variants.
