Human Thyroid-Peroxidase (TPO) ELISA Kit

Thrombopoietin (TPO), is a key regulator of megakaryocytopoiesis and thrombopoiesis in vitroand in vivo. TPO has been purified and cloned from several species including mouse, rat, and dog. The proteins from the various species are highly conserved, exhibiting from 69-75% sequence identity at the amino acid sequence level. Mature TPO can be divided into two domains: the amino-terminal half with homology to erythropoietin (Epo) and the carboxy-terminal half rich in serine, threonine and proline residues and containing seven potential N-linked glycosylation sites. The carboxy terminus domain of TPO has been shown to regulate the specific activity and circulating half-life of TPO. The carboxy-terminal may also have a role in promoting the efficient biosynthesis and secretion of TPO.

Human Thyroid-Peroxidase (TPO) ELISA Kit has high sensitivity and excellent specificity for detection of Human TPO. No significant cross-reactivity or interference between Human TPO and analogues was observed.

This Human Thyroid-Peroxidase (TPO) ELISA Kit employs a two-site sandwich ELISA to quantitate TPO in samples. An antibody specific for TPO has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTPO present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TPO 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 TPO 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.
