Human T-H glycoprotein (THP) ELISA Kit

Uromodulin, the most abundant protein in normal urine. Its excretion in urine follows proteolytic cleavage of the ectodomain of its glycosyl phosphatidylinosital-anchored counterpart that is situated on the luminal cell surface of the loop of Henle. Uromodulin may act as a constitutive inhibitor of calcium crystallization in renal fluids. Excretion of uromodulin in urine may provide defense against urinary tract infections caused by uropathogenic bacteria. Defects in this gene are associated with the autosomal dominant renal disorders medullary cystic kidney disease-2 and familial juvenile hyperuricemic nephropathy. These disorders are characterized by juvenile onset of hyperuricemia, gout, and progressive renal failure. While several transcript variants may exist for this gene, the full-length natures of only two have been described to date.

Human T-H glycoprotein (THP) ELISA Kit has high sensitivity and excellent specificity for detection of Human UMOD. No significant cross-reactivity or interference between Human UMOD and analogues was observed.

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