Invitrogen™ LIGHT/TNFSF14 Human ELISA Kit

Beschreibung

The Human LIGHT (TNFSF14) ELISA quantitates Hu LIGHT in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu LIGHT. Principle of the method The Human LIGHT 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.

Apoptosis, or programmed cell death, occurs during normal cellular differentiation and development of multicellular organisms. Apoptosis is induced by certain cytokines including TNF (tumor necrosis factor) and Fas ligand of the TNF family through their death domain containing receptors, TNFR1 (tumor necrosis factor receptor 1) and Fas. Cell death signals are transduced by death domain (DD)-containing adapter molecules and members of the ICE (interleukin-1-beta converting enzyme)/CED-3 (C. elegans death receptor-3) protease family. A novel DD-containing molecule was recently cloned from mouse, human and monkey and designated Daxx (death associated protein 6). Daxx binds specifically to the Fas death domain and enhances Fas induced apoptosis and activates the Jun N-terminal kinase (JNK) pathway. Daxx is widely expressed in fetal and adult human and mouse tissues indicating its important function in Fas signaling pathways.
