Description

QuicKey Pro Sheep Estradiol ELISA KitThe QuicKey Pro Sheep Estradiol ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Sheep E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Sheep E2 are added to the micro ELISA plate wells. Sheep E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2.

The QuicKey Pro Sheep Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Sheep E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Sheep E2 are added to the micro ELISA plate wells. Sheep E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2. 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 Sheep E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Well worth it
Color: Black & Grey, Size: Large
Great fit and not too hot. I really like these socks. They are comfortable, keep my feet warm without overheating them and the material is holding up well. The colors are true and they are not too thick that my shoes fit tight.

Socks
Color: Blue & Green, Size: Medium
They are about what I expected for the price. Nice and warm, but they pill a lot and sit higher on my ankle than I'd like. Very cozy and comfy though. Great around the house, not really great for hiking though. Kinda thin after a few uses outdoors. Washable but not very durable.
