The absorbance values are measured at 450 nm (optionally 450/630 nm) and are proportional to the concentration of the Beta 2-microglobulin the specimen
This Brain Derived Neurotrophic Factor ELISA kit uses the Sandwich-ELISA principle
The concentration of Human IL18BP in the samples is then determined by comparing the OD of the samples to the standard curve
The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm +/- 39 nm
EPHA1 (Ephrin Type A Receptor 1) ELISA Kit (Small Sample) Packaging:96 wells The absorbance values are measuredThe EPHA1 (Ephrin Type A Receptor 1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre coated with an antibody specific to Human EPHA1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin conjugated antibody specific to Human EPHA1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution
