Human ET-2 (Endothelin 2) ELISA Kit BRK-3 This C4 (Complement Component 4)

This C4 (Complement Component 4) ELISA Kit uses the sandwich-ELISA principle

The OD value is proportional to the concentration of Human DKK1

Only those wells that contain Human EDN

And then biotinylated Human ARHGEF5 Antibody is added and binds to ARHGEF5 in the sample

Human ET-2 (Endothelin 2) ELISA Kit BRK-3 This C4 (Complement Component 4)The Human (ET 2) Endothelin 2 ELISA Kit measures Endothelin 2 in samples. The plate has been pre coated with Human ET 2 antibody. ET 2 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human ET 2 Antibody is added and binds to ET 2 in the sample. Then Streptavidin HRP is added and binds to the Biotinylated ET 2 antibody. After incubation unbound Streptavidin HRP is washed away during a washing step.
