Human Thymic stromal lymphopoietin (TSLP) ELISA Kit

The cytokine thymic stromal lymphopoietin (TSLP) drives immature B cell development in vitro and may regulate T helper type 2 responses.Thymic stromal lymphopoietin, also known as TSLP, is a human gene.This 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. It mainly impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes and enhances the maturation of CD11c dendritic cells. Alternative splicing of this gene results in two transcript variants. TSLP is an interleukin (IL) -7-like cytokine produced by epithelial cells and triggers dendritic cell-mediated Th2 type allergic inflammatory responses.

Human Thymic stromal lymphopoietin (TSLP) ELISA Kit has high sensitivity and excellent specificity for detection of Human TSLP. No significant cross-reactivity or interference between Human TSLP and analogues was observed.

This Human Thymic stromal lymphopoietin (TSLP) ELISA Kit employs a two-site sandwich ELISA to quantitate TSLP in samples. An antibody specific for TSLP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTSLP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TSLP is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TSLP bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
