Ancillary Reagent Kit Available  

DY008, DuoSet ELISA Ancillary Reagent Kit 2 -

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Tumor Necrosis Factor-like (TL1A). The suggested diluent is suitable for the analysis of most cell culture supernate, serum, and plasma samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet.

Background: TL1A/TNFSF15

TL1A is a type II transmembrane protein belonging to the TNF superfamily and has been designated TNF superfamily member 15 (TNFSF15). TL1A is predominantly expressed in endothelial cells and its expression is inducible by TNF-alpha and IL-1alpha. TL1A binds with high affinity to death receptor 3 (DR3), now known as TNFRSF25. Depending on the cell context, ligation of DR3 by TL1A can trigger one of two signaling pathways, activation of the transcription factor NF-kB, or activation of caspases and apoptosis.
