Description

Bovine E3 (Estriol) ELISA KitThis Bovine E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Bovine E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Bovine E3 are added to the micro ELISA plate wells. Bovine 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 Bovine E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Bovine E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Bovine E3 are added to the micro ELISA plate wells. Bovine 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 Bovine E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

Truly fits wide feet!!
Size: 6 Wide Big Kid, Color: Purple/Turq
Runs true to size in length, and the wide is actually wide enough for my 10yo's duck feet!! My daughter wears a 5.5/6 so we ordered 6wide - great fit and nice colors! We love the Saucony sneakers that have the alternative closure aka velcro straps bc my girls still struggles tying laces tight!!

Pretty Good

These shoes are pretty good. The material has broken down faster than I anticipated but they have great support.
