ET-1 (Endothelin1) ELISA Kit (Small Sample) LDHD The optical density(OD) is measured

The optical density(OD) is measured spectrophotometrically at a wavelength of 450±2 nm

The OD value is proportional to the concentration of Human CD30

amphiregulin

The Porcine IL-8 (Interleukin 8) ELISA kit uses the Sandwich-ELISA principle

ET-1 (Endothelin1) ELISA Kit (Small Sample) LDHD The optical density(OD) is measuredThe ET 1 (Endothelin1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre coated with an antibody specific to Human ET 1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin conjugated antibody specific to Human ET 1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only
