Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL) is a member of the TNF ligand family. It can induce apoptosis in a wide range of cancer cells with no toxicity on most normal cells. TRAIL may also play roles in immune responses, autoimmune disorders and AIDS.
FunctionELISA Kits utilize the Sandwich ELISA technique to capture and quantifiably measure the amount of a specific protein present in a sample. Sandwich ELISAs use two antibodies that recognize different epitopes on the protein being studied. The first antibody is immobilized in the wells of an ELISA plate. When cell lysate is added, the specific protein of interest is bound by this Capture Antibody. A second antibody, called the Detecting Antibody, is then added. It binds to the bound protein. The FunctionELISA IκBα and TRAIL Kits use a horseradish peroxidase (HRP) or alkaline phosphatase (AP) conjugated secondary antibody that binds to the Detecting Antibody to quantify the amount of protein bound by the Capture Antibody (Figure 1A). FunctionELISA Cytochrome c utilizes a biotinylated Detecting Antibody and HRP conjugated to streptavidin for accurate detection of cytochrome c (Figure 1B).

Capture and Detecting Antibodies are used for sensitive, accurate quantification of the antigen of interest (Ag).
Why use FunctionELISA?
