  • Product overview

    TSLP Human protein in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of TSLP Human protein in serum and cell culture supernatant samples.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

  • Notes

    Thymic stromal lyphopoietin (TSLP) is a protein belonging to the IL-7 cytokine family. TSLP is released by epithelial cells and keratinocytes in response to trauma, infection or allergen. It acts upon dendritic cells to mediate TH2 mediated immune response and appears to be a key mediator in many inflammatory diseases such as: Asthma, Eczema, and Atopic Dermatitis. TSLP also acts upon mast cells promote the release of IL-5, -6, and -13 in the presence of IL-1 and TNF-α.

  • 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.
