Invitrogen™ TARC/CCL17 Human ELISA Kit

Beschreibung

The Human TARC/CCL17 ELISA quantitates Hu TARC in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu TARC. Principle of the method The Human TARC solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The 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. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Der TBOC-Ligand (CCL17) gehört zur CC Chemokin-Familie. Er ist ein kleines Zytokin und das Gen befindet sich beim Menschen zusammen mit anderen Chemokinen auf q-Arm des Chromosoms 16. TARC bindet spezifisch an T-Zellen und interagiert mit den Chemokinrezeptoren CCR4 und CCR8. Es spielt eine wichtige Rolle bei der T-Zellentwicklung im Thymus sowie beim Traffic und der Aktivierung reifer T-Zellen.
