TNF-Related Apoptosis Inducing Ligand (TRAIL) ELISA Kit


Human TRAIL ELISA kit is a procedure intended for analysing intended in vitro quantitative levels TNF-related apoptosis-inducing ligand (TRAIL) in human plasma, serum, saliva, cell culture supernatant and cell lysates. This assay has a minimum sensitivity limit of < 1.0 pg/ml.


TRAIL is composed of 281 amino acid sequence and possesses characteristics similar to a type II transmembrane protein. The C-terminal extracellular domain is found to be conserved and can also be proteolytically cleaved from the cell surface, whereas the N-terminal cytoplasmic domain is not conserved across family members. TRAIL can form homotrimer structures that have the ability to bind three receptor molecules. TRAIL can bind to the death receptors DR4 (TRAIL-RI) and DR5 (TRAIL-RII).

TRAIL is essentially a protein which functions as a ligand in order to induce apoptosis and this process is caspase-8 dependent. Caspase-8 activates downstream effector caspases including procaspase-3, -6, and -7, leading to activation of specific kinases. This whole process leads to transcription of genes which are known to antagonise the death signalling pathway and/or to promote inflammation.

TRAIL has also been designated cluster of differentiation 253 (CD253) and tumor necrosis factor (ligand) superfamily, member 10 (TNFSF10) – functioning as mediators of inflammatory responses and immune regulation.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
