Human Tankyrase-1 (TNKS) ELISA Kit

Tankyrase 1, a human telomeric poly (ADP-ribose) polymerase, was originally identified through its interaction with TRF1, a negative regulator of telomere length. Tankyrase 1 ADP-ribosylates TRF1 in vitro, and its overexpression induces telomere elongation in human cancer cells. Surprisingly, dissection of this domain reveals multiple discrete and overlapping binding sites for TRF1 and TAB182. Five well conserved ankyrin repeat clusters in tankyrase 1. Although each of the five ankyrin repeat clusters independently binds to TRF1, only three of the five bind toTAB182. These findings suggest that tankyrase 1 may act as a scaffold for large molecular mass complexes made up of multiple binding proteins. Potential roles for tankyrase 1-mediated higher order complexes at telomeres and at other subcellular sites.

Human Tankyrase-1 (TNKS) ELISA Kit has high sensitivity and excellent specificity for detection of Human TNKS. No significant cross-reactivity or interference between Human TNKS and analogues was observed.

This Human Tankyrase-1 (TNKS) ELISA Kit employs a two-site sandwich ELISA to quantitate TNKS in samples. An antibody specific for TNKS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTNKS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TNKS 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 TNKS 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.
