Invitrogen™ Human TSLP Uncoated ELISA Kit with Plates

Description

The Human TSLP Uncoated ELISA Kit contains pre-matched antibody pairs, plates and reagents for performing quantitative enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of human TSLP. Wash Buffer and Stop Solution are needed to complete the ELISA reaction and are sold separately. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.

TSLP is a 159 amino acid four helix-bundle hemopoietic cytokine that signals through a heterodimeric receptor complex consisting of the human TSLP receptor and the IL-7R alpha-chain. It impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes, enhances the maturation of CD11c (+) dendritic cells, naive CD4 (+), and CD8 (+) T cells into proallergic effectors, and primes dendritic cells to produce large amounts of IL-12 after CD40 ligand stimulation. TSLP influences the regulation of the positive selection of regulatory T cells and maintenance of peripheral CD4 (+) T cell homeostasis. It induces allergic inflammation by directly activating mast cells and may be involved in the pathophysiology of inflammatory arthritis. It is expressed in heart, liver and prostate.
