Description

Chicken E3 (Estriol) ELISA KitThis Chicken E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Chicken E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Chicken E3 are added to the micro ELISA plate wells. Chicken E3 in samples (or standards) competes with a fixed amount of E3 on the solid phase supporter for sites on the HRP linked detection antibody specific to E3.

This Chicken E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Chicken E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Chicken E3 are added to the micro ELISA plate wells. Chicken E3 in samples (or standards) competes with a fixed amount of E3 on the solid phase supporter for sites on the HRP linked detection antibody specific to E3. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450+/-2 nm. The concentration of Chicken E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

7 months after purchase
Size: 8.5 Wide, Color: Black
7 months after purchase. Still look good. Very comfortable right out of box. Outside edges of heels chipped away almost right away. Never seen that before. Brittle/ bad choice of rubber or design? Leather upper still looks pretty good with a little polish. Rubber soles wearing very well.
